@@dumkastriker not always. Agnostic gives u a strong lane presence so its good on support invoker and some though matchups at mid. Elitist is kinda bad at the moment because in lategame u have to auto people to get the damage amp on exort. And i think s&k is pretty bad on invoker now that he doesn't have spell lifesteal anymore
u outrange him so just auto the shit out of him. then go for cold snap + blood grenade or meteor + coldsnap at lvl 5/6. he instakills the forge spirits so consider building quas wex, he does nothing w/o mana. also, infused raindrops
There is a vídeo here in RU-vid that explains a Lot about Invoker and SF as mid heroes, is very good info vídeo but a little old. So maybe You can see it and learn something
im sorry there are so many moments that i see in this game that invoker could had done better e.g positioning and usage of spells. He picked agnostic but he builds like an elitist. Why even
