Achievement System [Character]

I'm making a shitty Achievement System, I need ideas for it.

This is what I have so far:
I created one achievement for when you get your first character level.


and that does this:

Which is the Title then the description and then gives rewards which are set from here


It's obviously not finished, mere start I suppose.

I need suggestions and opinions etc.
thanks.

Edit:
Changed it so the methods take a string not an int ("babysteps" instead of 1) etc.

Edit:
Changed the format of it all and added a quest for enemy kills - can develop from this for like Orxy Slayer quest etc (just have to be creative)

Make it so you can only get the achievement once, so just setup a simple db which stores 'achId'

make some type of achievement interface or something, so people can view their achievements and maybe add a claiming system their.

Maybe instead of notifying the player via chat, make it so that it notifies them via popup that doesn't interfere with actual game play, like that gift notification.

It's some really nice work, however I don't see why you'd add it for the character itself. The achievements for each independent character is given upon death, like, party members level up, tunnel rat etc. Making achievements for the account would be cool. But that is just my oppinion. Nice work

Couldn't having the achievement be a popup lead to unfortunate events? Rushing dungeon-> boom achievement popup-> boom dead?

I made this a while ago.
