Martial Casting [Warcasting]

Requires Half-Hand Casting Feat

You are skilled at using war magic in melee combat. You gain
the following benefits:
• You have advantage on Constitution saving throws to
maintain concentration on a spell when you take damage.
• When a hostile creature’s movement provokes an
opportunity attack from you, you can use your reaction
to cast a spell at the creature, rather than making an
opportunity attack. The spell must have a casting time of 1
action and must target only that creature.
