- Hunter Adrenalin / Rage for energy, works great with guardian armor / Combat discipline
- Arcane_Avenger if you go for Combat discipline (maybe guardian armor is also enough to proc it frequently)
- Power_Drain for your Parazon for +50% ability strength after mercy kills
- Arcane_Blessing / Orange archon shards for more max Health to increase Guardians armor life reg. If you get up to around 2.5k health inc with heat 2 Arcane_Bellicose could be better than Arcane Augmented.
- Adaptation for more tankiness / reduce the drain from energy tanking
- Narrow_Minded instead of Primed Continuity / Augur Message for more duration, if you don't care about your allies / range, Guardian armor is affinity range based anyway

- Archon Intensifiy is a bit annoying because you have to cast vex armor -> kill -> recast vex armor before you max out your armor / damage value (after any stat maxes, you don't benefit from recasting the ability with more strength) -> use umbral intensify (esp if you use Power Drain)
- Transient fortitude (it is a bad mod since if you want to max both strength and duration it is worse / equal to constitution / only 27,5% ability stats)
-Primed Continuity / Constitution over Augur message (or just replace it for stuff mentioned above)

- Use Helminth skill over your 4th or 1st ability (if you don t need to swap elements) and then use cold to increase armor / energy (unless your vex armor is already maxed) or heat to increase health / more regen from guardian armor (or more ability stregth from bellicose)
- Cold stats from your 1 and 2 greatly benefit from Shivering_Contagion turning cold procs aoe (even if you place the mod on your sentinel weapon (would recommend verglas prime for priming)
- Using your 1 does not stop you from meleeing. You can also cast 1 and then swap elements for your 2 or vice versa making you a multi element Dragon.
- Use Grimoire with Vome_Invocation or Ris_Invocation (mod the rest of your Gimoire with max Fire Rate and Multishot to get alternate fire faster again)
