[Solved] Spreading a buff to nearby units + hashtables

[DoomBlade]

Hello hivers. I have made 2 different custom damage over time skills with hashtables.

What I want to do next is a spell that spreads the buffs from the units that have the buff to nearby enemy units, 200 AoE or so. The best option would be if we could add the units to the already existing damage groups.

I have a couple of ideas how to do this, but they seem a bitt off.

The spells cast contains the buffs I want to use, adding them to the target. I managed to add the buffs only to one target by setting the AoE of the skills in the object editor to 0.

Icy touch = Frost Nova
Pestilent Strike = Acid Bomb

The both skills use the exact same method, but i'll post them both here, to see if someone can help me make the skill spreading the buffs.

I based the spreading ability on an instant cast spell (berserk in this case)

But i'm not too sure about unit group interactions when cleared on a spell cast basis, so might be best to get a second opinion.

Unfortunately the final trigger does not work as intented. If the unit only hass Pestilent Strike Buff, it will not spread it at all.

And if the unit has both buffs, the game freezes setting my fps from 200 to 0.1 with reforged graphichs, so it probably has a huge memory leak.

It spreads the icy touch pretty well tho, running really smooth, zero lag.

This was alot harder than expected, because I have to have all damage triggered in my map, due to use of DDS and custom spell critical and physical critical strike system.

As far as i'm concerned, it works really well with only having to spread one buff, but for some reason it stops working when you try to spread both buffs at once.

EDIT EDIT: It was working all along, I just had the DAMAGE INTERVAL of Acid bomb to 0.000. So it crashed the game. Problem was that all along, mistake in OE.
