Kalista's Soul-Marked supercedes FotM's/Targon's/Relic Shield's Spoils of War
This seems like it's probably an unintended feature and it's really annoying. If I'm laning while using Relic Shield (or any of it's upgrades), I'm unable to proc Spoils of War to get that sweet, sweet gold if Kalista attacked that unit. With the way her Soul-Marked passive works, its magic damage is applied before the Spoils of War execute. Since Kalista does the damage first, it means we can't share gold if she attacks minions I want to execute.
The few times that I've played with a Leona/Kalista lane, it synergizes really well, except for the difficulty generating gold as a support. Is this on Riot's radar? Is it going to be addressed in a patch anytime?
P.S. Cheers on the Kalista release, Riot: she's a really fun and interesting champ to play with.
