I realized that in my new kingdom Faithless, Hoarder and Miser are my last badges. Faithless I don't really worry about, as Vamp ticks it off automatically, and Miser I sometimes get by accident. Which officially puts Hoarder as my least favorite badge. Races are just so cool, I often feel that class doesn't matter so much as long as I have the right Race+Altar combo...
Anyway, decided to let come what may, and ticked it off on DL with the Tinker, who is fairly ideal for a Hoarder job (and luckily, I was also missing the Tinker badge).
I picked Gobs to remind myself not to convert anything, and was surprised to see how smooth the run went, despite not finding Fireball until I was practically out of blackspace. So that early Zot I was so glad to find, translocate and fire off was essentially wasted. GG -> TT run, last altar was Pactmaker but I didn't really need anything from him. After Avatar died, I went on to kill as many "???"s as I could, I got to 25 thanks to GETINDARE.
"Thinker", just without the "ache".
