EDIT: More bugs
The third hit on Mordekaiser's Q does not apply the Lich Bane effect. Not sure if intended or not, but it seems like a bug, as nothing is stated in the tool top.
1. Buy lich bane on Mordekaiser and use Q, use your first 2 hits. First hit will apply lich bane (so will second if you wait and use a spell to refresh the effect).
2. Activate a spell so you have the Lich Bane effect, and hit a minion, champion or monster. The lich bane effect will not apply.
EDIT: Does not apply ANY spellblade effects.
Titanic Hydra does not work properly with Mordekaiser Q (and other champs? not sure)
1. Buy titanic hydra
2. Activate Q
3. If Q kills target, it SOMETIMES doesn't proc the Titanic Hydra passive
Dragon's Clone deals %HP damage to turrets.
1. Kill dragon and make him into a clone
2. Have dragon attack a Turret. It deals Current % Hp damage. Does not work on Inhibitors or Nexus' (nexi?)
