I noticed the one originally by Torquil / Insane (i cannot remember which! If you know, please PM me so I can give credit where its due!) was removed, probably as it was old.

I took it upon myself to recreate it - and add in Giant Tortoises, and UAVs.

You can find the experience guide here, on my Google Sheets. I recommend saving it for your future use.

I'm assuming this is correct. I've not seen a way I can confirm this - Lioden doesn't disclose the Total EXP gained of any lion - so it is all maths.

I hope this helps some of you!
