Can you add masteries to the 2nd build?

Love the build, I have a question though. Why take Biscuits when you can take assassin?

What to say, nice guide. I still miss a few things from that, like being a bit more detailed. It's ok that Heimerdinger is not an initiator, but your teamfight damage can go two ways (three, but the third one is not that common). You can be a Veigar, and oneshot someone with ult+w. Or you can be the team player, who lays ult q in the enemy lines after the team started fighting, then quickly position turrets around fleeing foes, and then e+w the focused/secondary focus targets, so your team can kill most of them. The third way should be a team with lots of kinda mobile cleanups, the idea came right at this moment, so here it is: the usage of ult+e. if you get close to the enemy team, you can line it up, as it has three stuns. If you immobilize your enemies, then your cleanups can approach, and kill them in a matter of a second. This is a fast way, but unreliable, as it is not tested if I'm right.

Sorry for judging things as this guide stands still, but I have to admit that I mained Heimerdinger from level 20 to level 30, and today I'm experimenting with the kit he provides.

Great guide! I've been trying to take up the ****er once again, but I couldn't pull it off. Your help is quite appreciated.

Ive tried the build, it works pretty well, but imo you should buy the zhonya's first, because you will get ganked early game, and the zhonya really helps you to survive the damage and get atleast 1 kill, other then that, its good
