Not entirely sure what part(s) of this post are bugs or if they are working as intended as it involves a lot of talent nodes across skills that change interactions. I hope I explained it well enough to make sense (I kinda hurt my brain thinking about this haha)
To provide some info, I am specced into:
- Swarmkeeper’s Call (Swarmblade Form) → Hives replaced with Healing Totems + release all locusts when transforming into Spriggan Form
- Spiked Vespiary (Swarmblade Form) → Hives cast Thorns instead of releasing Locusts
- Titan’s Bane (Thorn Totem) → Thorn Totems only shoot 1 max thorn per shot
- Spiked Totems (Spriggan Form) → Healing Totems directly cast from Spriggan Form also shoot thorns
Bugs
With my current setup, my hives do not get replaced by healing totems when swapping from Swarmblade into Spriggan Form. Healing Totems get added on top of hives’ their location
It does not seem to be a visual bug, as if I go back into Human->Swarmblade form, I can still hit my hives to release thorns (through Spiked Vespiary). Also quite sure I’m still seeing hives cast thorns after they should have been replaced
I’m pretty sure this is a bug, but I also have some questions about interactions and if there are possible bugs in them.
Questions about interactions / Potential bugs
- Is it intended for the interaction between (1 and (2 to not work when locusts from hives have been transformed into thorns?
Right now it feels like Spiked Vespiary takes away the ability to release neither locusts nor thorns. Instead it hard casts thorns (not release). Therefor the interaction between (1 and (2 doesn’t work as there is nothing to release?
This could potentially explain the bug of hives not disappearing either as they can’t fully release their… load 
EDIT: Spiked Vespiary does not take away the ability to “release neither locusts nor thorns”. Confirmed with Release the Horde talent node.
- If I’m wrong in above presumption, does the interaction between (1/(2 and (3 have something to do with it?
Swarmkeeper’s Call makes it release “all” locusts(+thorns?), but since Titan’s Bane limits Thorn Totems to just 1 projectile per shot it kinda bugs out or something? To be clear, I’m not seeing any thorns shot from hives after shapeshifting
- Should Healing Totems spawned through Swarmkeeper’s Call inherit the benefits from (4 Spiked Totems?
Currently I can see my Healing Totems (transformed from hives) shooting thorns, but I did not “directly cast them from this tree*” as Spiked Totems mentions in its tooltip.
/* I assume you need to directly cast them from Spriggan Form? Though I have to admit I like this interaction and wouldnt mind it staying like this.
