Mortilys goes in at E for general , S for PvP and D for HP boost , with the lowest defence and HP possible and a moveset that’s basically terrible apart from one move this is a very all-or-nothing design that relies almost entirely on specific team building. Either you need to play this in the front line with slow teammates or intend to line it up to get a turn after you use moves to put the rest of your team on high TU. Initially I was incredibly skeptical of this working reliably, but now I realise the way to make this work is using monsters at +0 and when you meet an opponent who doesn’t have their monsters at +5 or above hopefully they’re not a strong opponent (at +5 you have most of the entrance speed already). You can also always fall back on the SS to shield your team. When it does work, you’re able to get a free turn with your whole team. Beyond that, you have two choices: either you remove it (bear in mind backstab will set your monster back by 150s so you’ll want to sendback instead) or you’ve created your setup with high TU monsters that allow you to shriek again and push back the enemies. It seems like particular setups will be incredibly brutal like this. For specific PvE battles Mortilys will be a useful tool but otherwise it won’t have much purpose.
Crazy how many people underrated this guy initially (not that I didn’t either after the Wooloid fiasco) but I did think he was an above average stun absorber for not having a weakness and punishing the opponent for killing it but I didn’t think hellish shriek would be it’s ultimate skill. Beautiful monster so I’m okay with it being meta.
