Hi folks, I am wondering whether Manabond Trap/Mine is even viable?

I made some tests, and the line: "+6 to length per 25% of Unreserved maximum Mana you have" does not seem to work for Traps, since they do not have any mana i guess? In POB, the trap damage scales with Mana, as it normally would: "Deals base Lightning Damage equal to (25-44)% of missing Unreserved Mana". poewiki does not clarify anything, so maybe you guys can?

Anyway, here's the PoB i made. The numbers are good kinda good, mechanically speaking it should also be really good.

INFO - Potentially about 10-15 divs budget, could be more/less if optimised better. Tried to keep okay'ish damage and survivability

About 8 mil DPS, could be more if traps trigger an additional time

75k ehp

MoM Agnostic setup

Non-Meta shit

Potential to oneshot bosses i guess?

Crit, Curse and Elemental Ailment immune
