Just a comfy build for making the grind faster.
Put any other arcane if you want, I just find these work best for me with this build.
Hope it helps you.

Possible Changes

• Use something like Synth Fiber to make the most out of Equilibrium.

• Zenurik's Energizing Dash can help you drop Dispensary faster and Energy Pulse to make the most out of it.

• Use the Decaying Dragon Key to get that 1.3 seconds (when fully recharged) faster instead of just 0.33 seconds (when still not back to full), by using your skills with the help of Augur Mods.

• If you want to make the most out of your Dispensary, you might want to consider using Health Convertion for more survivability (same goes in a slowva build with Energy Convertion for even more strength in your abilities and not using Transient Fortitude to keep duration). Also Synth Fiber and Synth Deconstruct could help you utilize convertion even more often (a Djinn / Vulpaphyla with Reawaken/(Crescent Devolution/Panzer Devolution/Sly Devolution) could help you have these mods active almost always).

• If you can kill fast enough, consider Martyr Symbiosis as an extra layer of survivability with your Vulpaphyla.

• If you want more survivability, you can change Escape Velocity with Mobilize (or just Forma for the Exilus Mod) and Augur Message with Adaptation.Also sidenote, DO NOT REPLACE Escape Velocity WITH Coaction Drift, as it does not work with Power Donation (or Growing Power for that matter), so it is useless (or as the wiki says it "(Coaction Drift) does not work with Growing Power nor Power Donation").

• Due to the Dispensary, you don't need Arcane Energize for more energy, so you cna try to go for more tankiness with Arcane Grace or more damage with an Arcane Avenger/Arcane Arachne.
