The Explosive Spear Tip Testing Challenge is a very short side mission that takes place at the Donglu Research Station in Wuthering Waves. The quest is a sort of mini-game where you will need to take control of a cannon and shoot down targets with exploding spear tips.
There is a scoring system involved and if you can reach the maximum score under one minute and thirty seconds then you will get additional bonus rewards. These bonus rewards include Union EXP along with a lot of Shell Credits and Resonance Potions.
Below is a detailed guide on how to complete the Explosive Spear Tip Testing Challenge in Wuthering Waves.
How to start the Explosive Spear Tip Testing Challenge in Wuthering Waves

As mentioned, to start the quest you will need to make your way to the Donglu Research Station. So teleport to Huanglong-Port city of Guixu Nexus and then head northeast.
You will come to some ruins and inside a destroyed building you will find the NPC standing behind a cannon. Talk to them and begin the Explosive Spear Tip Testing Challenge.
How to complete the Explosive Spear Tip Testing Challenge in Wuthering Waves
After talking to the NPC, start the challenge by interacting with the cannon right infront of you. The goal is to shoot the targets with explosive sper tips and rack up some points.
Here are some tips to keep in mind to get the best possible outcome in the mission:
1) Take “projectile drop” into consideration
The spear tips have a sort of arching animation. So the farther away the target, the more will the tips drop before reaching it.
For targets that are at the very end of the shooting range, place your crosshairs a bit above them before pulling the trigger. This will make sure that you hit your target.

2) Be wary of the targets that have a red line across them
From time to time a different target will pop up which glows red and has a red line cutting across it. These targets cannot be shot down and will block your line of sight. Wait for them to go before starting to shoot again.
3) Make the most of the exploding targets
Some targets in Wuthering Waves’ Explosive Spear Tip Testing Challenge will explode when hit taking down any other target that is near it.
You can use this AoE effect to take out multiple targets in one-shot.

4) Pre-emptively shoot moving targets
Some targets will oscillate in a fixed path. You can pre-emptively shoot at a point where they will arrive to make it much easier to destroy them
5) Reach a score of over 5,000
One minute and thirty seconds is more than enough time for you to reach a score of over 5,000 in the Explosive Spear Tip Testing Challenge. Make sure you reach this mark to get the bonus rewards.
Rewards for completing the Explosive Spear Tip Testing Challenge

The mini-game will end when either the timer runs out or you cross a score of 5,000. The base reward for the quest is:
- 2x Medium Resonance Potion
- 2x Medium Energy Core
- 1x Medium Sealed Tube
- 3,000x Shell Credits
If you beat the score of 5,000, you will get additional chests which cumulatively offer:
- 50x Union EXP
- 15x Astrite
- 1x Wooden Textured Shard
- 1x Medium Resonance Potion

While it’s one of the shorter quests in Kuro Games’ RPG, the rewards are pretty neat and can come in handy.
