Scale mail seems a bit redundant, doesn't it?

it's not a scale mail, it's a padded coat :P
(He wears no armour)

Protected by sheer awesome. Okay.

in fact it's a power that grant his Wisdom bonus to his AC, like a Monk

I need to get back playing D&D.

Do it, do it now :D

I never thought you could actually make a Kobold Character in D&D.

You can play any character you want, as long the GM is good with that. Kobolds are an available race in the recent versions of D&D, tho Draselth is a Pathfinder character to be more accurate.

Interesting. This makes me wanna play D&D more now. X3

Also, this is just an observation, but how come he has a sword? I thought clerics couldn't use bladed weapons.

There are many ways a cleric can get a sword. In Pathfinder, clerics receive proficiency with their deity's favourite weapon (in his case the Longsword). Otherwise you can take the martial weapon: Longsword feat. Also possible is to multiclass in a class that grants proficiency with the use of the weapon you want.

Interesting. What edition of D&D is this in?

This can be applied for D&D 3.5 and Pathfinder, tho the Cleric in D&D 3.5 doesn't start with the deity favourite weapon by default (you can ask the GM) or you can look up for ways to give them the weapon you want, if you dig long enough in the other rules books :P

The inquisitor class is in Pathfinder.

For the multiclassing part works for both games. It's fine to take one level as another martial class (ie: Fighter, Ranger, Rogue) to start with additional martial skills, armours and/or HP when playing a spellcaster
