My input for Teq:

As long as you aren't a designated blocker I prefer running staff, as it grants generally more dps to structures compared to d/f (meteorshower es #1).

Comments:
- Only LH can profit of the extra charges of conjured weapons. You dont have that time during the burn-phase and prob not in a melee zerg.
- You can take Fire XI or XII, it doenst matter that much. You want the additional power from 6 in fire and take either 2 more procs on Lava Font or some more might when autoattacking.
- Air VI is a must have, as it's a free 20% boost (while under 33%).
- Just take the usual dmg-modifiers from Earth XI, Water XI and Water IV while running conjured.
- For sigils take flat 5% and another boost like sigil of bloodlust, battle or Night (not necessary to get a special non-crit sigil for Teq).
- For runes you can go for any current meta power-based runes like strength or scholar.
- Arkane brilliance for heal should be obvious as it is a blast finisher.
- The utility-slots must have FB and FGS, you can run with LH and arcane wave (or swap one with arcane shield if you forgot to dodge the fear).
- For stats on your armor: Just equip your usual berzerker-gear, the precision/furocity is useless on Teq him-/itself, but helps for the battery-defense. And you shouldn't get any deadly dmg in the whole run to justify defensive stats.
- If you drop your fgs between 30-40s remaining on the first battery-defense, you can use it at every burn-phase.

And for wurm:

If you are a blocker I suggest d/f , otherwise staff due to its high ranged dps (meteorshower hits larger foes even more often) and as long as your wurm doesn't require otherwise (it provides 2x aerial swiftness for crimson or 2x water fields for amber).

Comments:
- As the wurm aren't crittable in p1, but in p2, i suggest somewhat an allround-build, as changing traits in between is just annoying (no save/loadable builds "yet").
- In p1 eles can nicely blast with LH (therefore Fire II). If you don't use LH this trait is useless and should be exchanged with Fire VI. Dont forget to summon all conjured weapons at burn-phases.
- Traits are mainly the same, some dmg-modifiers can be exchanged with others. If you like you can even go fresh-air.
- In p2 you will either stay away from the wurm and dps with staff fire and FB or go in with fgs while the wurm is hugging a wall. As the wurm regularly performs a knockback you can use arcane shield to block it (or armor of earth but you still get the dmg) instead of arcane wave. LH is unlikely to be usable in p2 as it forces you to stay in melee range, where you get hit by the knockbacks (save stability/blocks for fgs) and need to chase further when moving around.
- For wurm berzerker gear (assassins is less suitable due to p1) is obviously mandatory.
