So, i’ve been experimenting with Rex and i have decided to post my current understandings about him. Please note, this guide is being written on Rex’s release, some it may contain some inaccuracies.
I’m gonna be straight about this. I’m 100% positive that Rex’s kit revolves around his Mouse 2. Anyone that played him even once will agree with no argument.
But let’s discuss this skill in detail:
- Rex’s M2 strikes for an astounding 450% damage Aoe. It costs 15% CURRENT hp, meaning that if you have 100 hps it will cost 15, if you have 50 it will cost 7,5 and so on. and due to this, you can’t kill yourself with it. But can get real close to it. Good job!
- Despite being called a mortar shot, it’s really not. It’s not blocked by any ceiling, rather, Mouse 2 will just generate an explosion in a designed area after a minor delay.
- It can be held in order to aim. Else, the cast is almost instantaneous. I really feel like aiming is unnecessary, if you just tap it on your target it will never miss, since the skill it’s pretty fast when it comes to striking.
- It has about 1 sec cooldown, probably a little bit less.
- It has no range limit. Meaning that it can be used to snipe across the map.
- Rex’s m2 has little to none cast time, and we’ll see what that means in a second.
Now that we understand his M2, we can talk about business.
Mouse 2: Cancels and Interactions
As i mentioned, Mouse 2 has no noticeable cast time. What that means Is that as long as you press mouse 2 first, you can sequence any skill without any noticeable delay. You can Mouse2 → Mouse1. And you’ll fire the triple shot burst From your mouse 1 along with your mouse 2 mortar shot. You Can Mouse 2 → R, and you’ll fire the two things at the same time, but, note that R is a slow-ish travelling projectile. You can Mouse2 → Shift, in order to stop that stone golem from firing his laser shot at you, or just because you needed that mid-air mobility. Oh, and speaking of that, you can even m2 → jump (duh).
These are all useful, but i’m gonna tell you a big secret. Your Mouse1 fires three shots, with the third one healing you and weakening the target. The problem is, Mouse two is a spammy spell that drains your health quickly, and the healing from Mouse 1 is not that great. But i have you covered.
There is a really simple combo to get 2 procs of your healing between your Mortar casts.
It’s as simple as this: Mouse1 → Mouse2 → Mouse1.
What happens is: You shoot your three projectiles, and immediately after the third one goes off, you fire M2 just by tapping while aiming at your target. And if you payed attention, you know that you can chain a Mouse1 just right after mouse 2.The final result is that you fire a shot, and before the third one hits you spend your health for mouse 2, so that the first proc of healing won’t go wasted, and then you immediately follow with another one.
Some things to note are:
- If you press mouse 2 too quickly, you may end up cancelling your third shot from your first mouse1. Don’t you be doing that.
- This “combo” (?) really helps, but unless you have a Backup Magazine, or A Syringe, it will only work once each two spell rotations.
No, I won’t talk about every item in the game. Nonetheless, even though I definitely need to update this guide later down the line, I have found some synergies and somewhat interesting things to talk about.
First off, Medkit will proc normally each time you spend life on a M2 or R. We’re all disappointed when we get one, but on Rex it’s actually pretty decent in order to mitigate your self damage.
Secondly, The Bustling Fungus is really helpful. Sometimes. Point is, if you stand still you get the sustain from it and you can become the living embodiment of a WW2 artillery cannon, as the magical shroom restores the health you’re spending. You can camp a spot if you’re 100% sure it’s safe, but you’re no Engineer, so you don’t have that x3 value on your shrooms. This all sounds pretty good, but don’t forget that despite the heals you’re still hurting yourself so it’s easier to burst you down. If you want to make use of this strategy make sure you’re both safe AND playing with someone else that can take aggro. And keep an eye on your surroundings, or you’ll blow up in no time no matter what. I promise.
Due to M2 having a short cooldown, getting a Backup Magazine makes your damage output skyrocket. Unfortunately, so does the damage you inflict on yourself. I’ve heard people argue that it’s useless, but I disagree. The point i’m trying to make is: You’re no Huntress either and it’s not mandatory at all. If you wanna take the trade it’s a fine choice, but know that you don’t need more than one, or two if you feel cocky.
Shields are not considered health. Therefore they are not expandable in order to cast your skills. And by god’s sake don’t go Transcendence.
