Destructo Merc Maxed Equipment, no POB, help

https://maxroll.gg/poe2/planner/b46tg00i

Hi, on my fourth dawn hunt league character. Sold everything from previous to fund explosion Merc after falling in love.

Full screen insta wipe, delete bosses. Very fun. Bit of a glass cannon but with very high move speed just git gud. Can kill everything before it can react so death not a concern. Explosive shot, explosive grenade, artillery, triple herald.

Issue, my PC died and can't access POB. Any tips on passive tree improvements or w.e else would be welcomed. I don't think I have growth potential for gear any more.

Crafting and selling maps has funded this monster.

Second weapon slot uses same crossbow, megalomaniac/rare jewels swapped.

Thanks for help!
