I second Red Lotus. The reason you would use this over a nuke is because I find that nukes almost never give me SP, while weapon attacks & WS give SP at a decent rate. It will run through your MP quickly though....which may be a problem if you don't have the THM MP regen abilities.
I also use MAR Defender ability when soloing. (reduces physical attack, increases defense). I confirmed that it does not effect Dart damage or heals. It does seem to help how much damage a CON takes even cross-class. I wouldn't level a MAR up to 10 solely for it, but if you already play Marauder it's useful when soloing.
Isn't it still on cool down once you swap weapons out of combat? Or can you have it loaded on con swap to Tha and it doesn't go into cool down since it was loaded on con????
The latter, it's not on cooldown once you switch jobs/weapons.
I use both Tranquility and Exaltation on my Pugilist this way, and get 100% MP refill every 5 minutes.
Since both are zero cost skills, there is no reason that either ability should ever not be equipped, i keep them on action bar #3 so that they don't take up space on my main action bar. Edited, Oct 20th 2010 1:29pm by ixion13
