I remember...my first time i cast a fireball. I was lvl 5 Invoker and believe me i was waiting for this spell 3 months since i got the appropriate level for castin lvl 3 spells. I was ready to burn a group of hostile orcs and kobolds and goblins and.... Then suddenly 4 skeletons where in front of me guarding the entrance of a cave. I said to my company members:

Me:"Let me transform their bones into dust!"
Party:"Oh yes great Wizzard, get rid of these skeletons as soon as possible"

I took the components i start casting the spell..."fire bla bloom boom" (the words) and 5 D6 in their face!!!

Final Damage: 1 + 1 + 2 + 1 + 1 = 6 HP

Guess what? The skeletons saving through was succesfull so the actual damage was 3 HP. They had 5 HP each.

Imagine what happened!!! Everybody was laughing at me!!! I still cannot forget this moment!

Really, Pen and Paper RPG gives you great moments. You should try this but i suggest you play with your friends. There is a lot of fun in this game!
