[Meta thread] Iron's PokeRole Adventure: The Skull Ruins

[Dragonstrike]

(this means that I start, right? what's the +5 for though, I don't remember reading about it.)

Yep, you got the highest result, so you react the fastest.  The +5 is from your stats, in this case, your Dexterity plus your Survival.  The total of those and 1 D6 roll is your Initiative.

Okay, thank you!  
The D6, does it mean dice rolled (6)? sorry, I'm still very inexpirenced with these mechanics

When DnD players say D6, they mean a Die with 6 sides.  They also use D20, D10, D4, D8, and D100/percentile dice.  Pokerole only uses D6 though.  The (6) Iron put down is the result he rolled on the Die, being a 6 this time.
