Since it's hard to keep the mana bulb filled for this build, would it be worth thinking about builds using PS as a 1-pointer (or at least, as a non-primary skill)? Some examples off the top of my head:
1. Max singularity, 1 pt PS (or more?), 20 Doom. Go for high energy and regen as in the full-PS build.
Singularity does phys dmg so Doom will help a lot.
Use PS mainly as a heal, but with max energy and regen approach the damage may be decent too, so it may be like a bottomless healing pot that also fries a few crispy critters while you heal.
2. Maelstrom throw build.
This will use Doom so it will get 1-pt PS en route.
It maxes dex so the PS damage may not be worth worrying about but it uses
Void
Void
Weapons
'Sur'
Runeword Level: 75
Adds 7-13 Damage
+(58 to 72)% Enhanced Damage
Slow Target 20%
Regenerate Mana +15%
Cold Resist +40%
Physical Damage Reduced by (11 to 15)
+(3 to 5) Mana on Striking
2% Reanimate as: Random Monster
or
Void (Xis)
so after pumping a few PS to heal, it can refill the mana bulb with a few throws.
Just throwing some ideas around. Any mileage in builds using PS as non-primary skill?
