On paper Tohelo’s riftmage reinc looks nice: you can kill up to 5k..8k monsters instantly with Golden arrow, Int is over 300, spmax is around 1500, Spr around 150, and so on.

However, I noticed that at least with fire entity (currently large), riftmage is slower than monk at solo exp:

Couple of two hour solo exp sessions as level 60 human monk(tarma):

Session summary:                                                         
Time: 1 hour 46 minutes 30 seconds                                       
Experience gained: 959590                                                

Session summary:
Time: 2 hours 7 minutes 39 seconds
Experience gained: 990753

Same as level 55 human riftmage (with large fire entity):

Session summary:
Time: 2 hours 17 minutes 27 seconds
Experience gained: 796818

Session summary:                
Time: 2 hours 4 minutes 7 seconds
Experience gained: 775718

NOTE: In all cases, I have had full exp pool when I have started the exp session.

Partially the difference can be explained by the poor tanking abilities of my fire entity combined to poor healing abilities of human riftwalker (my Wis is only around 90, so Regenerate rift entity doesn’t heal much).

Monsters have also been slightly different, but I suspect that in the riftwalker sessions the monsters have been in a better tune.

I could start carrying Wis set in addition to Int and Spr sets to solve the entity healing issue, but at the same time I would prefer to keep the playing simple.

Also, switching to air entity allows one to shoot Golden arrow (or any other offensive non-riftwalker spell) more than once, so you could start killing bigger monsters and potentially that way increase the exp rate.
