Just a follow up to my question in case anyone runs into this. I ended up passing the target info to the EffectManagerDCC script, and that worked. It didn't work for damage because the targeting is set to "all" instead of "each" in the GameSystem script. Here is the code I changed in my ActionAttack script (added text in bold):
Code:
local nDiceChainMod, nDiceChainCount = EffectManagerDCC.getEffectsBonus(rSource, {"DIEATK"}, true, aAttackFilter, rTarget);
Kelrugem, you were exactly right. I thought I tried this already, but apparently not.
Cheers!
