Greetings,
Recently I've been testing how exactly the #upmarmu spell interacts with the Brawling Skill and the Speed Skill. My conclusion is that, since it overrides the attack, it overrides the Speed Skill's speed boost. On the other hand, it stacks with the Brawling Skill and yields higher damage, though the attack delay is not great. I've been playing around with the spell on a local test server and I've put together a version that seems to scale pretty well in terms of attack speed and damage in relation to STR and AGI. Attack delay is around 700-800 with only 1 AGI, but it can get up to 110 if AGI is maxed out at 138 (set on an exponential curve). DPS with an iron potion on Brawling, with max stats, and with assassin gear is about 2600, which is a bit less than what I've achieved with the assassin gear on the Speed Skill. The difference is that my tweak makes the attack have a 100% success rate, though the spell doesn't last very long.
I'd like to suggest the implementation of this modification on the Legacy server (if the TMWA team approves) to help make the unarmed fighter a bit more realistic (it probably isn't better than a tank, though this would make it almost invincible one on one).
Sincerely,
