Can you tell me the rulings for Killian, Ink Duelist?
user
0. If a spell has additional costs, apply those increases before applying cost reductions.
1. Killian can reduce alternative costs. For example, if you choose to pay the {1}{B} alternative cost for Baleful Mastery while targeting a creature, that cost would be reduced to {B}.
2. Killian, Ink Duelist can’t reduce the colored mana requirement of a spell’s mana cost.
