Quick Answer
Find the Trident outside Obmuer Temple, then attack enemies with it until it levels up and breaks. You can use the broken piece as a key in the temple room with several trident keyholes. These doors lead to extra loot, so you do not need this key for main progression.
Where do you find the Trident?

Reach the area outside Obmuer Temple

Keep using it until the head breaks off
Keep attacking enemies until it hits its top level and the head breaks off.

Where do you use the broken Trident key?
You use the broken piece in the Obmuer Temple room containing the third save point and several trident keyholes.
Take it back to that room and use it on one of the trident keyholes. With three Trident Keys you can open the gate to the chest holding the Engraved Halberd.
Where are all four Trident Keys?
| Trident Key | Where |
|---|---|
| 1st | In the watery area near the temple entrance, after you drop down |
| 2nd | Up where a couple of skeletons ambush you, near the third Wind Gem |
| 3rd | The head of the Trident, after you level it until it breaks |
| 4th | Sold in the shop after you beat the Tower of Knowledge boss |
The Trident Keys open optional loot rooms. You can finish the temple without them.
