Belkar adquired in Tinkertown the talisman that allowed him to kill Durkula

[Ginasius]

I was going to write "High Priest of Hel" instead of Durkula, but the title was too long.

Actually it is a cloak clasp that is equiped with a Protection from Evil spell to block compulsion magic.

It happened in strip nr. 969.

Of course, it was actually Mr. Scruffy who activated it and reanimated Belkar. A clever animal; not for nothing was he the de facto ruler of Azure City for some time.

Im going to "invoke" to the user who just reactivated a thread three yers old asking this question.

Probably O Chul learned to be resilient and endure all the hardships of fate in the years when he had to oblige Mr Scruffry's demands for poopsies.

So you are saying that O'Chul's awesomnes derives from Belkar lying to a gnome?

That's my new headcannon.

He clearly earned that high CON score cleaning thousands of litterboxes over the years.
