Combat Caster (feat)

War Caster

War Caster is considered one of the most powerful feats in Dungeons & Dragons 5th edition, and it becomes even more powerful with some Hyrulean content. Consequently this version of the feat is slightly weaker to compensate—it only enables a cantrip as an opportunity attack, as opposed to a spell of any level.

Prerequisite: The ability to cast at least one spell

You have practiced casting spells in the midst of combat, learning techniques that grant you the following benefits:

• You have advantage on Constitution saving throws that you make to maintain your concentration on a spell when you take damage.
• You can perform the somatic components of spells even when you have weapons or a shield in one or both hands.
• When a hostile creature's movement provokes an opportunity attack from you, you can use your reaction to cast a cantrip you know at the creature, rather than making an opportunity attack. The cantrip must have a casting time of 1 action and must target only that creature.
