Hey,
Runic invocation has many different spells for example (lighning/ fire) “plasma blast” which cost 29 mana. Since its cost 29 mana it can easily trigger brand of deception in the runemage passive tree, because it cost over 15 mana and deals an on hit.
If u take the passive interlude on runic invocation u always cast a 2 rune invocation. So if i take (lightning / fire / fire) “hydrahedon” it also cast (lighting / fire) “plasma blast” which still cost me 29 mana. The problem here is brand of deception doesnt get triggert any longer.
Thanks Nordicsturm.
