I used to run orber with some extra.
I got a hydra/orb on this ladder and it rules.
Ofc a bit slow when fire immunes and static + TK is also slow - but it can clear all

20 orb, 1 mastery, no synergy, 1 tele, 1 static, 1 tk and then the rest in first 20 hydra and 20 fire mastery ---
- and then as you level up further, you can decide depending on where you want to be faster during the rushes really......
Static to 10 could be a good move.. or perhaps even more... depending on your liking....
Hydra synergies should be prioritized for the rest as orb will work with 20/1/1 .... (plus static..)
