Mordekaiser - Abilities
Iron Man (Passive): 20% of the damage dealt from ability is converted in to a temporary shield. Maximum shield strength is 450.00 health. The shield decays by 15.00 per second.
Mordekaiser's unique mechanic. This is what allows Mordekaiser to tank, makes him useful in teamfights, and makes building him different than other tanks. At first, the shield will seem fairly small, but by mid-game it is a significant barrier.
Mace of Spades: On next hit, Mordekaiser swings his mace with such force that it echoes out, striking up to three nearby targets, dealing his attack damage plus bonus damage. If the target is alone, the bonus damage is doubled. Deals attack damage plus (20/40/60/80/100) bonus damage.
A powerful ability than can charge your shield all the way in one strike if there are enough enemies around. You get more benefit from your attack damage than the bonus damage, so get this at level 2 and leave it unlevelled until late game - it's powerful enough as it is. Use this to harass heroes and to clear creep waves. The bonus damage makes it excellent for ganks as well.
Creeping Death: Unleashes a protective cloud of metal shards to surround an ally, increasing their armor and magic resistance, and dealing damage per second to enemies caught in the cloud. Increases armor and magic resistance by (10/15/20/25/30) and deals (16/32/48/64/80 +.1 per ability power) to nearby enemies.
A great tanking and harassing tool. Put at least a point in this early so that you can charge your shield from a distance. It is also helpful in mitigating early game harassment and doing some in return. The armor and MR boost is significant, so use it when tanking or in a teamfight.
Siphon of Destruction: Mordekaiser deals damage to enemies in a cone-shaped area in front of him. For each unit hit, Mordekaiser's shield absorbs energy. Deals (65/110/155/200/245 +.25 per ability power) damage and gives (8/12/16/20/24) additional shield charge per unit hit.
Your best harassment and defense tool. Hitting a full creep wave with this will charge your shield almost to full. The range is large nad the damage is not insignificant, so try and hit enemy champions in the wave as well - you are more than capable of wearing them down with just this. Level this first.
