For starters Ive tested this on a couple of servers. It might now work for all.
1.First you need a char. that is noblesse.
2.Make sure your fully buffed with all the buffs you want and stuff with Noblesse ( Very Important you have Noblesse)
3.Get your self to low HP
4.Next activate the skill you want Frenzy Zealot Angelic Icon or such
5.Then have a Guard or friend kill you. (If you take off your armor to die faster make sure you requip it before you die)
6.Once your Dead wait till the skill Frenzy, Zealot, Angelic Icon, or w/e you have runs out.
7.Once the skill runs out spawn back to town.
The buff wont be on your bar but you well have the attributes still that those buffs gave. Some key things to watch out for is if you get another buff or any skill that effects your stats it well remove the glitched buffs ( This includes changing weapons, armor, and even getting a greater heals that leave the dot on you)
Gl HF Works great with Titans.
