So I was looking into "New Character Options" as a failsafe against my current character dieing and I stumbled upon the MoFW. At LV12 he gets "Slow Time" which means he can spend 6 Ki Points to gain 3 Standard actions in one round. I thought back to my musings on Vital Strike and lo-and-behold it only says Attack Actions which are types of Standard Actions.
So at LV 15 with Ki to burn and Improved Vital Strike, a Mofw could move 80', spend 6 Ki and do 3 attacks at BAB +11 for 6d6+3d6(Energy); OR 6d10 if using a Monks Robe. That's a damage spread of 9-54 per attack or 27-162 per round and only deducting DR/Hardness three times.
Am I missing something here? That sounds like a whole lot of damage in one round + moving, & if you've got WIS 20 then you could do that twice per day. (as your Ki Pool would be 12).
You can only do one Elemental Fist attack per round.
And anyway, for level 15, investing in that many feats, and burning half your Ki, that's really not that much damage.
Look at Dragon's Roar instead, standard action cone attack dealing unarmed damage plus you can add on Elemental Fist, chance for shaken.
ok, so 4d8 x 3 three times (+3d6 Energy) in one round after moving 80' if you're large... in which case you also get 10' reach is still 36d8+3d6 or a spread of 39-308 with and average of 172.5 damage and if you wait just one more level you can easily blow through Large Stone gates and Huge Wooden ones at the head of a charging cavalry formation. Or take down a most golems reliably. Still seems a bit over the top given that the round after you can probably full attack as a followup with 6x4d8 FOB (7 @ LV16). You're a one man siege engine.
