Publisher's blurb:
This supplement fleshes out SPELLS and introduces brand new mechanics for ICRPG: METAMAGIC SPELLS and FEATS. Take your magical knowledge to the next level!
METAMAGIC SPELLS are special SPELLS that let you cast another SPELL with modifications like double damage, double duration, no cost and so on. There is one that lets you even cast two spells with a single action!
FEATS are special abilities for characters that let them do extraordinary things. Characters gain them in place of milestones. This will let you play games without LOOT if you wish so. Mechanically, FEATS are similar to SPELLS but activating a FEAT is a free action and you can activate multiple FEATS one after the other. Also you master FEATS individually and mastering them lowers their activation cost.
Extra attacks, extra actions, marking, parrying, cleaves, ducking, dodging, stat boosts… You name it.
