Specialist: Royal Taste Tester

Local ability: Tastes the kings food to make sure it's not poisoned.

Global ability: Tastes all of the peoples' food too make sure it's not poisoned.

The royal taste tester is a defensive specialist that can prevent against poison. You wouldn't want someone to poison your food right? This is important.

"I'll taste you're food."

I see. There is some balancing issues I would like to adress...
Can he taste my "food"?

OMG we need this!!!!!

I've been waiting for years for somebody to taste my food!! I almost started but now the food taster is here to save me!!

This is a bit OP. I mean, come on. Taste everyone's food? That's not fair. They could never get poisoned, which is one of my best attacks.

But: what if the taste tester finds poison? He dies, doesn't he? One time use?

If you stack two Testers do you get 4x the flavour?

Can he be promoted to royal butler? 2x food serving speed?
