So, this guy has a very good reality stat already with okayish armor. No need for reality mod here. But, with max red skill, his armor went up by a pretty decent number around the same as reality. So, no need for armor mod as well.
Interesting thing is in white & green skill, his damage is Orange which means this will increase as basic damage increases, his normal crit is also good & need +69 to have 100% of Crit.
So, I would suggest giving him 3 BD mods which increase his basic damage & eventually his damage from white & green skill & go with normal crit on all 3 mod to reach 270 normal crit.
Now, his purple skill won’t get evaded by evasion as curse is debuff & debuffs can’t be evaded so need to upgrade this skill for toons with high Evasion.
Also Skill mods can’t increase his damage so avoid them here.
So, 4th Mod would be an interesting one, as giving purple & blue upgrades won't make sense here, Green does damage & stun the attacker every 10 seconds which can be evaded or reduced.
I am not suggesting to put 4th mod as BD mod because at max 4 BD normal crit his stat will be 329 & for super crit ( 3x damage ) you need it at 370, so you have 59% chance of 3x damage, if you are okay with RNG then you can go with 4 BD normal crit, if you are low on resource you can also go with 4 BD mod just to reach +69 distributed over 4 mods.
If you are able to reach +69 with 3 BD mod, then Fourth mod should be Green Skill so that davy can also disable the toons
