Zeal Artifact Set

The Zeal set is a 2-piece Artifact set that grants C. DMG +20%, +3% damage for every 25% HP this Champion has. You can stack up to three sets on one champion for a total of +60% C. DMG and 36% damage boost, which is great for DPS champions in both PvP and PvE.

This set can only be obtained from Live arena. This is the best 2 piece set for damage dealers in the game, giving a huge damage boost when the wearer is at full HP. It also pairs nicely with Merciless gear as well. You can still use strong individual pieces as off-set gear when stats matter more than set bonuses.

Zeal sits as the improved version of Crit Damage, but maybe just beneath Merciless. Although in some situations it is better than Merciless when they have DEF ignore already. Although this set is arguably harder to get hold of, due to some people not liking Live arena.
