Yes, cover most definitely affects Eldritch Blast in Dungeons and Dragons (D&D). The rules for cover are clear: obstacles between you and your target can make them more difficult to hit. This applies whether the spell shoots a straight beam or has some other visual effect. Walls, trees, creatures, and even smaller obstacles can provide cover, increasing a target’s Armor Class (AC) or granting them a bonus to Dexterity saving throws, depending on the degree of cover. Thus, knowing how cover interacts with Eldritch Blast is crucial for any aspiring Warlock.
Understanding Cover in D&D 5e
What Constitutes Cover?
The Player’s Handbook outlines different types of cover:
- Half Cover: A target has half cover if an obstacle blocks at least half of its body. This grants a +2 bonus to AC and Dexterity saving throws. Examples include low walls, furniture, or creatures.
- Three-Quarters Cover: A target has three-quarters cover if an obstacle blocks about three-quarters of its body. This grants a +5 bonus to AC and Dexterity saving throws. Examples include a portcullis, an arrow slit, or a thick tree trunk.
- Full Cover: A target has total cover if it cannot be targeted directly by a spell or attack.
How Cover Works with Attack Rolls
When you cast Eldritch Blast, you make a ranged spell attack roll. If the target has cover, you must meet or exceed their AC including the bonus granted by the cover. For example, if a creature has an AC of 15 and half cover, you need to roll high enough to beat an effective AC of 17 to hit.
Considerations for Eldritch Blast’s Multiple Beams
Eldritch Blast becomes unique at higher levels because you launch multiple beams. The rules don’t explicitly state that all beams are affected if one source of cover exists. Most Dungeon Masters (DMs) rule that if any part of a creature is behind cover, the attack on that specific beam is subject to the cover rules.
Strategic Positioning: Remember, clever positioning can minimize the effects of cover. Angle yourself to gain a clearer shot, or consider moving to a different location entirely.
Cover significantly impacts ranged attacks and spellcasting in D&D, making positioning and tactical awareness crucial for both players and DMs. If you are interested in the intersection of games and learning, then check out Games Learning Society or visit GamesLearningSociety.org.
Frequently Asked Questions (FAQs) about Eldritch Blast and Cover
1. Does Spirit Shroud affect Eldritch Blast?
Spirit Shroud adds extra damage on hit, but only if the target is within 10 feet. It does not directly impact whether cover affects Eldritch Blast. The positional requirement of Spirit Shroud must be considered separately from cover.
2. What does Eldritch Blast scale with?
Eldritch Blast scales with your total character level, not just your Warlock class level. This means a multiclass character gains additional beams at the appropriate character levels regardless of their Warlock level.
3. How close can you cast Eldritch Blast?
Eldritch Blast is a ranged spell attack. Ordinarily, casting a ranged attack while within 5 feet of a hostile creature imposes disadvantage on the attack roll. The Warlock can, with the Repelling Blast Invocation, pull enemies closer after hitting them with the blast.
4. How do you get the most damage out of Eldritch Blast?
The Agonizing Blast Eldritch Invocation is key. It adds your Charisma modifier to the damage of each beam of Eldritch Blast, substantially boosting your damage output. Other damage boosters, like Hex or Hexblade’s Curse, can be added for even more damage.
5. What affects Eldritch Blast damage?
Eldritch Blast damage is primarily affected by your Charisma modifier (via Agonizing Blast), other damage riders (like Hex), and critical hits. Specific items and feats might further augment the damage.
6. Can you quicken Eldritch Blast?
Yes, a Sorcerer with the Metamagic option Quicken Spell can use a sorcery point to cast Eldritch Blast as a bonus action. This allows you to cast another spell, including another Eldritch Blast, in the same turn.
7. Why is Eldritch Blast considered the best cantrip?
Eldritch Blast is highly regarded due to its customizable nature through Eldritch Invocations, its scaling damage, and its force damage type, which is rarely resisted. The ability to push, pull, or slow targets further enhances its utility.
8. What is the longest possible range for Eldritch Blast?
With the Eldritch Spear invocation (300 feet) and the Spell Sniper feat (doubling the range), you can extend the range to 600 feet. A Sorcerer can use the Distant Spell Metamagic to double the range, which can reach up to 1200 feet.
9. Can Eldritch Blast be twinned?
The Twinned Spell Metamagic can only be used on spells that target one creature. At early levels (1-4), Eldritch Blast only targets one creature per cast and can thus be twinned. However, at higher levels (5+), Eldritch Blast can target multiple creatures, making it ineligible for twinning.
10. Is there a hidden advantage to Eldritch Blast?
One subtle advantage is that each beam of Eldritch Blast requires a separate attack roll. This effectively gives you multiple chances to score a critical hit or overcome a target’s high AC.
11. Can you cast two Eldritch Blasts in one turn?
Yes, you can cast Eldritch Blast multiple times in a turn by using features like Action Surge (from the Fighter class) or Quicken Spell (from the Sorcerer class). Each requires a separate action or bonus action.
12. Can you curve Eldritch Blast?
Eldritch Blast does not inherently curve. Each beam travels in a straight line to its target. However, you can target creatures you can’t directly see as long as you know their location, effectively “shooting around” obstacles.
13. Is a Tarrasque immune to Eldritch Blast?
The Tarrasque has high defenses, but it is not inherently immune to Eldritch Blast. However, its high AC and legendary resistances make it a challenging target. Some campaign-specific Tarrasques might have unique immunities conferred to them by divine intervention.
14. Do you roll for each beam of Eldritch Blast?
Yes, you roll a separate attack roll for each beam of Eldritch Blast. If you hit, you roll damage separately for each beam as well. This means you make multiple attack and damage rolls per casting at higher levels.
15. Can Eldritch Blast hit allies?
Normally, Eldritch Blast targets only your intended targets. However, the Dungeon Master’s Guide provides optional rules for “Hitting Cover,” where a missed attack might accidentally strike a creature providing cover to the intended target. This optional rule could result in Eldritch Blast inadvertently hitting an ally if you miss by a significant margin. In the basic rules, if a creature grants your target half cover, you are able to hit that creature, but only if your attack roll would have hit that creature instead of the target behind them.
Ultimately, understanding the interplay between Eldritch Blast and cover, along with its many other facets, allows you to maximize its effectiveness and tactical utility in your D&D games.
