I've been playing around with Hildryn for a couple of days, and I'll be really honest, at first I thought that this shield gating wouldn't work, but to my biggest surprise, it does!
Although she does indeed need a few tweaks, she feels really fresh and engaging, so good job on that.
Let's start with the passive:
Really good as is. Gives her that much needed safety window in case she runs out of shields. I would personally give it a little cooldown, because of a certain specific build that can make her totally invincible, although at the cost of not being able to cast any ability. Anything between 5 and 10 seconds sounds fair.
Now let's move on to her abilities:
Teased as powerful and efficient, it sadly isn't.
The drain is way too much for the result we get. Yes, it deals damage, but it still doesn't make up for it. I would rather use any of my equiped weapons instead.
I'd suggest to reduce its drain, and speed up the charge rate.
Hildryn's bread and butter. We got it, she works around this ability. A well designed ability... that still needs some QoL tweaks.
It's good in open worlds, but in closed spaces, not so much. The ability is sometimes clunky if the enemies are at a different height level than you, and most often than not, the enemies in front of you already got killed by your teammates, which is why I think the LoS should go away. To balance this change, the other abilities' drain could be increased, and SP's range reduced.
Also, the casting animation, while being able to be cast mid-air, still takes too much time, leaving you vulnerable to enemies' incoming fire. I would suggest to either reduce its casting speed, make it a one handed cast ability or shortly stagger the affected enemies.
Overall, an amazing ability, that gives that well-rounded support touch to Hildryn's kit.
With the sugested change to her Shield Pillage, I'd recommend to slightly increase the drain.
The black sheep of the group. Feels really underwhelming and overall, not what is expected of an utilmate ability.
I'd start by adding a significant speed boost, since as of now it feels really slow, totally not how you'd imagine a jetpack, and the max ceiling should be adjusted in open worlds.
Let us use Shield Pillage during this ability. Needless to say that without being able to use Shield Pillage, our shields just vanish in a few seconds.
Tweak Balefire so it deals double the damage, and not be just a visual dual wielding. Leave the charge rate and drain as is, and drastically increase its explosion area.
Finally, same as Shield Pillage's bug, enemies at a different height level aren't affected by it.
Possible idea: let us use our weapons while using this ability?
Hildryn's Primary and Secondary color channels give a "washed out" effect to our colors, which isn't really aesthetically pleasing. The textures are pretty low quality (same problem as Mesa Prime when first released), this can easily be seen when using black colors. Also, some of her parts can't be colored at all.
The Surator Syandana's Primary color channel darkens the color used, same problem for some parts of the Secondary color channel, turning bright white into grey.
