Hey there,
Just wanna share an interesting idea I´m currently using:
You can trigger Rune of Hagarrad as soon as a +1RoH item is being un-equipped.
I exploit this by switching weapons right after I place the rune.
This way RoH is being triggered instantly, making for a much more comfy and imo powerful gameplay.
Ofc, one will have to pass on aura-giving components, but I think it´s worth it.
Moreover I switch weapons automated via AHK script.
If this is new to you and appealing, have fun! 
Thanks, good to know, probably won’t use it as it wouldn’t be good for a build guide.
I think it’s just RoH pet dying and exploding just like other pets
do you have to lower your 26/16 in RoH for it to explode earlier?
I wonder if it then loses damage because of that
or maybe you can have i.e. 28 (more points than needed for max) and lower it to 26 for it to explode?
cooldown doesn’t reset I assume?
cooldown does not reset, ofc 
the rest i dont quite understand…
The rune is placed with the stats of the weapons being used. If you un-equip them, the rune triggers - also with the weapons that WERE used when placing.
Me, I simply place 2 twin sets of hand/off-hands in my slots.
If you use completely different weapons for the switch, one COULD think of yet another advantage. I just dont see one, yet.
Omg, I just tested it and it works as you described and feels amazing.
The whole idea of my recent build was to play melee caster for all projectiles of RoH to hit all the time.
With this trick you can basically play ranged / kiting RoH without losing damage. I need to rethink my life now.
Although this build has Shadow Strike so ranged is not so feasible / practical.
But I have another build which is ranged / RoH hybrid so I guess I could use it then.
Btw I’ve found one scenario when it doesn’t work
when you switch to weapon set with higher RoH skill points
seems you need to have <= skill points in RoH after switch for RoH to explode
Neat trick. Thanks! 
Yeah, completely legit and never ever nervable.
Nice side effects:
2nd weapons could be off hands (if you use RoH dual-wield), for Devastation, AAR or AAR-like spells.
1st weapons could be items that strongly push your non-RoH attack, while 2nd weapons could be RoH-pushing items (spectral longswords for example) - with respect to TQfans observation: no higher RoH levels.
Again: I rly can recommend using scripts for the switch, or TQfans Autocaster.
Its super fluent this way.
Yeah…don’t get used to this exploit.

Ok. /10char
Heh. Dunno how you didn’t see that one coming lol. I thought everyone knew an exploit is an exploit and that Zan would be coming to crush your fun 
it isn’t like this is the first time they’ve had to smash weapon-switching exploits.
Yeah, they really seem to hate weapon switching, and at the same time refuse to simply disable it.
Honestly, I thought many people including devs were already aware of that Rune-thing. Wasn´t expecting it to be put on the crush list right away. I mean, it comes with downsides.
I don’t think it’s that they hate it, it’s more that it causes all kinds of problems that can be hard to foresee and anticipate with various skills - as evidenced by the number of exploits people have managed to find because of it.
And it isnt even just GD… numerous games have problems like that because of weapon switching (and it boils down to cancellation of effects etc). An old game, Gunz Online, had a whole style (k-style) and ecosystem derived directly from the “bugs” of weapon switching.
I mean, ship has sailed on removing it for GD, but I’d absolutely not bring it back in a sequel.
It’s way too niche and either ends up useless, generates weird edge cases, or we have to balance around using it at which point everyone that doesn’t like it also has to use it too to be optimal.
