Elephants in SK seemed sparse to me for ones that gave XP. I think at 24/25 you can start doing the sabertooth in LOIO, 13 on map by the windmill.

Can prolly do the spiders via dog charming or root rot to 24 to begin the sabertooth. Been a while since I leveled druid so don't recall where else in low 20s you could charm.
