Need to clarify on his ability. Do he gain the health and fatigue on the following situation?
1) When heroes within 3 spaces on him stand up and gain the health/fatigue by rolling the 2 red dice?
2) Passive ability of Varikas The Dead? Do Mok gain the fatigue as well?
3) Health pot and fatigue pot drink by heroes?
4) Surges used by other heroes to recover fatigue during attack?
5) Heals receives by other heroes 3 spaces away from him?
6) Any other abilities or skill that trigger by other heroes which leads to recover of health and fatigue.
Also the ability does not mention once per turn so I believe this can trigger multiple times. And if all the situation I mention above can trigger his ability, I think he can be officially crown as the King of Leech. LOL!
