Undead Guardian

Undead Guardian is a medium priority Secret Shop pet. It is only obtainable in the Secret Shop. Undead Guardian enhances medal buff gained from transcended undead units. It is really good in increasing your overall medal percentage buff, with priority dependant upon number of undead units transcended.

Generally Orc Guardian has much higher priority as Battle Drummer is the best unit for boosting the buff from the revival team.

Upon reaching 5* this pet gives the 7* artifact:Undead Hero's Staff.

Skill 1 increases medal buff by X%. Example: at 1*, T3 Undead Unit gives bonus of: 30%+ 30%*20% = 30%+6%= 36%.
