Boosting!

[Mercurio]

Go to straholme now.

I levelled my last few characters in Stratholme from 45-58.
I did one full run to get the key to the side entrance, then just cleared undead side, and all the undead mobs on the live side (left the scarlet compound).
I didn't do the baron runs and pretty much two runs would level the team.

I used the same strategy to level up like 5-6 teams. Works very well. BTW, 45 is the min level to enter Strat, so enter now and it is the sweet spot.
