Holy crap is he powerful.
Even against A.I., this character is the most consistently successful Demigod in the game. He needs a slight nerf.
From previous posts I am compelled to reiterate: keep his Mines from becoming active for as long as entities are in the viscinity, or add a 5 second delay to them becoming active. Regulus in the current build utilizes his Mines offensively, like mortar shells. He already has a crossbow and associated abilities to take it to a foe... heaped upon that are the new 'curse' abilities. Altogether these make Regulus very powerful. He does not need "grenades".
