Tips for Allies

  • Turret placement can be a deciding factor in a battle. Against most enemies turrets are best when they can support each other, but if the enemy has a lot of area of effect damage your turrets can be destroyed quickly. Placing turrets in brush can lead to a surprise attack in your favor.
  • The success of Electron Storm Grenade is very important to Heimerdinger's survival. The slow and stun both are capable of keeping enemies in place long enough to punish them, but it is also the first line of defense against a surprise attack.
  • Spreading out Hextech Micro-Rockets leads to more reliable damage and more efficiency against multiple targets, but focusing it creates the biggest impact.

Tips for Enemies

  • It's better to destroy all of Heimerdinger's turrets at once with the help of creeps than to fight them one at a time.
  • Be wary of Heimerdinger's Upgrade!!!, as he can use it to find an answer to most trouble he gets into. Once his ultimate is down, go in for the kill!


From the Journal of Professor Cecil B. Heimerdinger



Current meteorological conditions in Bandle City seem optimal. Atmospheric pressure is ideal for today's experiments!

Running a fifth trial for my Tridyminiumobulator this afternoon. Some fine tuning is required; singed my mustache. Need to adjust the energy throughput.


Tridyminiumobulator is still not maintaining intended proper energy efficiency! Necessary to run more numbers. In the meantime, I have found something else that's very intriguing.

While returning home after today's tests, I passed a gaggle of young yordles throwing a spherical projectile at each other. It's a simple enough concept: throw the object at someone, catch it, throw it at another yordle, repeat. But yordle miscalculations result in several errors! They throw with inconsistent accuracy and force, and the ''ball'' (as they refer to it) is frequently dropped... There are many ways for this process to be improved. According to my calculations, and after collecting data from the participants, if the pitching was consistent in both speed and arc there would be a 44.57% increase to fun! I need to ponder this for the evening.



Eureka! I've devised a solution.

I've invented an automated ball pitcher. Current name: H-28G. It employs a consistent speed and trajectory, ensuring that the recipient will always be able to catch the ball. It redirects itself to the nearest yordle (if there is more than one in the vicinity) ensuring everyone has a turn. I'll take it to the young yordles today and demonstrate my invention.

Also: spilled toxic acid on my shoes this morning. Bothersome.


Tested the automated pitcher today. It did not go as planned. The young ones were excited enough about my invention, but, when the machine was turned on, it was far too powerful! Even at its lowest setting it completely knocked a yordle off his feet. Clearly, I overestimated the velocity behind their throws... I'll return soon to make adjustments.

But my priority, for now, is the Tridyminiumobulator; I must fix its complications before lunch. Once it's in good shape, I'll need to test it somewhere else. Bandle City is proving insufficient for field research.



Apparently, there's a giant in town. A highly annoying anomaly. The noise outside is disturbing my research!

Must check fish tank today. They've been strangely quiet...



I have heard that many yordles have been injured due to the giant-related disturbance. If this doesn't stop soon, intervention will be necessary! I hope H-28G is still intact. I would lose a lot of time if it has to be rebuilt.


Everything is quiet again. It seems that the giant came to his senses and ran off. I need to gather H-28G tomorrow, once I've finished with more pressing matters. I've almost perfected the Tridyminiumobulator!



Today has been quite eventful already. I was surprised by a knock at my door. It seemed like the entire city was standing in front of my house. Normally, when a crowd has gathered, it's because they have some petty grievance about my work. But this time, they were celebrating!

Astonishingly, it seems one of the young yordles took advantage of the H-28G prototype I had left behind amidst the giant tomfoolery. He proved to be innovative, and repurposed the invention into a makeshift turret. It's powerful enough to scare off a giant - imagine that! What an ingenious little fellow.

I wish I could employ his like-minded encephalon in the near future - I have big plans and his assistance could be valuable - but he'd have to leave Bandle City. The scope of my plans necessitates a more expansive testing ground.

Runeterra should suffice!
