I like the Punch Art formula change, as it would make the physical damaging parts of Punch Art more accessible.
Kikuichimonji (Katana): 10 WP, 15 W-EV, Earth element, 50% Cast: Kikuichimonji, Forced 2H, 3 Range, but can only hit the farthest tile (think Dictionaries and Harps)
The 3 range thing is probably more fitting for Heaven's Cloud. Which means... Kiku still needs a real design >_>
Heaven's Cloud (DO) at 3 AoE does indeed sound like good, stupid fun.
I'd be willing to give it a shot. I think max damage would be 28*6 = 168 (Squire with PA boosting gear + 108 Gems/Prismatic Rod for Strengthen). Actually, if Netherseer becomes a thing, I would vote against 3 AoE, but if Netherseer can't make it for some reason, then 3 AoE HC sounds good.
Possible Spear designs! Copy-pasted from an earlier post of mine + adding a couple new ideas:
Spear with 50% Don't Move proc
Spear with 50% Power Ruin / Mind Ruin proc
Spear with 33% Undead proc
Spear with 100% Consecration proc
Spear with 50% cast Life Drain proc (redundant with Blood Spear, but this encourages high Fa Lancers, possibly even 40/70!)
Spear with 50% cast Stop (someone else had this idea before)
Spear with 50% Blade Beam proc or 50% cast Balance proc
Spear with 100% Knockback (is this possible?) (ok maybe it shouldn't be 100% but it sounds funny!)
Spear with 50% cast Execute (possibly bonkers)
Spear with 75% cast Last Dance (overall result is 30% CT 00)
