Ok so i finally got all the charms for 74 summoning and i really want to get it, but first i want to find out if its actually worth the 4.4m im going to be spending on shards and 2nds? From 71 to 74 i unlock a few good familiars like the Obby Golem and the one i want the most which is the Rock Lobster. However, i dont want to spend the 4.4m on getting the 3 lvls if its not going to be worth it in the end.

The best levels are 40->52->67/68/69->79->88+ (they all get better once you hit 88)

 

Obby golem hits well for its level as does rock lobster. If you fish a lot rock lobster will not only speed it up, but also make you a nice chunk of money too.

yea most of the plan with the rock lobbie was fishing boost and him gathering fish for me. The golem i was planning to use in order to boost my mining lvl and also to use as a combat familiar for the slayer tasks that i wont need my bunyip for healing.
