Rules as Written:
You need to be within 5 feet (melee engagement range) of your target to cast a spell with a range of “Touch”.
You need a successful attack roll against AAC 10 in order to successfully touch an opponent in combat (to use a Touch ranged spell against an unwilling target).
- Do you need an empty hand in order to cast Touch ranged spells (on willing or unwilling targets)?
- Note: There are bigger implications for the Cleric / Druid Cure Wound class spells and the Necromancer Cause Wound class spells, but these are not the only implications.
- Most obvious implications are for shields or torches. Two-handed weapons, less so.
