Has anyone participated in a group that someone has utilized this style?
My concern is higher level, say even 15th or 20th level, where a character can have 3 or 4 attacks. Let's also add in Additional Foes, so character can attack multiple enemies in one round.
Using the costs, it would take the cost to from 1/3 to 2/4, assuming single weapon and these two options.
15th level Fighter, 30 ranks, Common Man with 90 in St and Ag, with +10 item, has an OB of 149.
With the style, the fighter can make 1 attack OB 149, two attacks at OB 129, 3 attacks at OB 109.
Let's even make this against three opponents, one attack each, OB 89 vs each opponent.
Now at 20th, these become OB 169, or two at OB 149, or three at OB 129. VS three opponents OB 109.
On paper, this looks unbalanced, especially then adding Adrenal Strength or Speed.
Has anyone seen this in action? Did it unbalance the game?
