Shoot Strider Canisters using Fire Arrows. Fairly simple yet challenging. Shoot off the canisters one by one. If you shoot them all at the same time you could risk blowing off one of the canisters without them exploding. It takes time for a canister to explode, after you've shot at one, shoot another one off a different Strider to save yourself time.

SHOCK TRIAL
Stun Bellowback and Shoot Canisters off the Undersides. You can either use the shock arrows or shock grenades to stun Bellowbacks. Its important that they are stunned first before you start shooting at the canisters, they are also protected by a single armor plate. Destroy it first with a single hardpoint arrow then quickly switch to Fire arrows or Freeze arrows depending on which kind of Bellowback you are dealing with.

FREEZE TRIAL
Kill Machines while Frozen. For this trial, go after the Striders instead of the Bellowbacks. Striders are easier to kill which you want in order for you to gain those Blazing Suns. Use Freeze Sling ammo or Freeze arrows to freeze them and then take them out quickly with Critical Strikes or aiming for weak spots.
