@RenzFlintrock, um okay? i'll try my best to that. honestly i just go though my available characters and their Pokemon and make them do things that would be appropriate in the situation based on the relationships they have.
honestly what the two did isn't difficult. if you break down what Angel and Agnes are doing along with Amphy and Flash, they are doing far less than what your thinking about.
1. Angel is shooting and deflecting arrows with bullets but NOT from everyone, only for herself and Maker who is near her at that point since she helped her to her feet just before and is protecting her as it was clear that was what she wanted to do. she doesn't know the rest of the group and could care less if they got hurt or died. (nothing personal it's ust how the relationship is right now)
2. Angel ordered Flash to used Magnetic Flux to draw arrows to him, again not a very big area Flash is not the strongest of Ampharos, and Amphy to use protect near him to block the arrows so he doesn't get bodied.
3. Agnes fires shots to deflect arrows with bullets and moves towards Amphy and Flash, she's not confident she can hit every arrow coming at her at a consistent rate.
4. Agnes spots Ino in trouble and calls her to take cover near Flash, Amphy, and herself.
5. Angel receives Intel from Agnes about the general direction of where enemies are, and there are numerous to her knowledge so Angel decides to fire a special AOE shot that nearly leaves her drained of mana at where she thinks is a decent concentration of enemies in an attempt to neutralize them.
That was what they did.
Are there more archers? Yea probably, would be pretty dumb to be clustered in a singular area when they got a whole tree line.
what are the rest of the people doing? arrows are raining on them, Angel was only protecting herself and Maker, Agnes was protecting herself and a bit of Ino. Amphy and Flash has a small area of somewhat safety.
There are plenty more things to do for everyone to do for one thing how are they avoiding the arrows? what are they doing to try to counter attack? , Angel and Agnes only did what was in their character to do at the given situation with what resources they had.
