Tectonic Slam of Catclysm does not branch visually

Tectonic slam of cataclysm does not visually branch, but deals damage to monsters outside of visible aoe.

I consumed 10 endurance charges, which means 100% branch chance. This means the slam should branch every possible time, dealing damage in shape of leaf. However it visually branches just once or twice, while dealing damage outside of affected area. As you can see in image below, only the main fissure from tectonic slam is visible (red color), but monster died outside of that area (blue color). Its quite hard to get this into screenshot, but on maps i can clear whole screens of monsters, while there is only visual of the main branch. Currently I'm using celestial tectonic slam effect, but it does the same thing with normal tectonic slam

+1, i have the same visual bug

I have same problem only when Ralackesh boots equipped. Without them everything looks normal. Is it only visual bug?

I have this problem with or without boots. It seems only visual as i clear screens of mobs with every slam.

experiencing the same thing, regardless of mtx

There are lots of bug reports on this. TSoC has been bugged since league start. The AoE, damage, and branch chance are not scaling with endurance charges at all.
