This is a Terminus guide made by a Terminus main with ~75% W/L and over a hundred matches played. This guide will focus on one build that relies on good timing with the Syphon. With this build, you can out-damage the dps and add a lot of pressure on the enemy tanks, especially Inara and Barik.
This loadout focuses on Calamity Blasts. Necromantic Might V will help you gain a lot of charges fast, and with Devastation V you can gain a maximum of 1250 HP with them. With this combination, you can regain (almost) 25% of your total health every now and then. I usually also run Forsaken III, so I can gain even more charges. Hitting 2 things with one swing will give you the double amount of charge. This also counts for shields and deployables.
Decimation is a must-have, the extra 100 damage will definetly show results.
For Items, it really depends on the Situation. Rejuvenate is always a good pick however. Caut too, if you don't get enough support from your dps on the point.
Here are other upgrades that I also occasionally recommend:
Bulldozer: A must-have when fighting Barik or Inara. Focus on the deployables (except the wall) when fighting them. An unlucky Barik will use a turret-based loadout, and be countered very hard.
Nimble: Everyone says that this is THE upgrade for Terminus. Although it is useful, it is not always the best. You only need Nimble if the enemy is faster than you, causing you to miss your swings. However, on the point, you don't need to chase. In fact, you can usually finish off enemies with your calamity blast. Get this upgrade if flanks are getting on your nerves.
Morale Boost: Your ult is very powerful in theory, so Morale boost will help for sure right? Depends on how you use it. Your ult causes enemies to scatter and let you respawn right there. However, once it's finished, you'll probably die in 3 seconds if your team doesn't push. I recommend using your ult during overtime, so your enemies will be forced to leave the point and ending the overtime. Other than that, you can use your ult if your team is going to do a push. Even if you're on the flank and you'll hit nobody, an extra frontline in a push is always useful.
Resilience: Depends on how much CC the enemy has. That's all there is to it. Being CC'd as Terminus makes you an easy target.
Most other upgrades don't really mean anything special to Term, and are kind of generic. Upgrades I do not recommend using are:
Wrecker, Kill to heal, Life Rip, Veteran, and Chronos (your only cd is Shatterfall, don't bother)
Again, take Decimation.
Reduce the damage required to generate a Calamity Blast charge by 600.
Heal for 300 for each enemy hit by Calamity Blast.
Generate 10% of a Calamity Blast charge for each enemy hit with Massacre Axe.
Increase your maximum Health by 150.

Each Calamity Blast deals an additional 100 damage.
Receive 5% more healing from other players.
Against Barik and Inara, you MUST buy Bulldozer. You're one of the few champions that can just jump in and destroy the turrets/stone. Unlike others, that will be blocked by their shield/wall. Other than that, you can jump over Inara's wall if things start heating up.
When you're fighting a Ruckus, just keep putting your Syphon up and down. Ruckus will either stop shooting during his build-up or just feed your Syphon.
Drogoz depends on how you and Drogoz play, but if you can flick your Syphon well, you can deny Drogoz' rockets completely. When he ults you, walk back, and then leap over him. Stall him as much as you can, and if he gets you you still have your ult. You can also use your ult to commit a 'Get down mister President!'.
You can't go wrong picking Term against these guys. This is mostly because of either their splash damage or because you can block a lot of damage. Remember to buy Resilience against Ash and Atlas (only if Atlas keeps putting you back).
Extra tip: When Viktor ults, aim your Syphon at the CENTER of the mark. This will 'catch' the explosions, giving you a lot of charges and a wasted Viktor ult.
These champions don't pose a big threat to you and you can't really get to them either. These champions have a lot of mobility but don't do much to you without getting close.
Talus can be tricky, but it's a high-risk high-reward situation when fighting him. He will usually feed your Syphon and teleport back in a team-fight, but can destroy you if he's flanking you on your own.
Watch out for these guys, those tanks will stun you 24/7 and can go right through your Syphon.
Snipers are very dangerous, but you can copy their rythm with your Syphon. This can be very hard to do when they realize what you're doing.
Also, never, EVER ult when Androxus is still alive. Unless you know 100% sure his reversal is down, don't bother. Androxus can be an easy kill if he tries to Syphon your axe tho (which doesn't work anymore).
1. Combine your swings and blasts.
A lot of newcomers forget this. You lose almost no time when you put a blast in between your swings. When used right, you can deal 2*700+350=1750 damage in a little more than 2 seconds, even more when you have more calamity blasts stored. This can deal a maximum of 3150 damage. This is enough to kill any squishy.
2. Shatterfall isn't 'used' until it lands.
See it as this, once you press F, the ability is 'active'. However, it isn't on cooldown yet. As soon as it lands, it's 'inactive' and the cooldown starts. If you got Resilience, you can use this to gain extra distance/height by jumping into stuns like Furia's beam.
3. Use shatterfall at places where the ceiling is low.
If you hit the ceiling, you will drop right back without the full animation. With this, you can combine shatterfall with the other combo. It also leads to you being less vulnerable using the ability.
4. Protecting others is the #1 priority.
A lot of people, especially the experienced ones, know to not shoot at Terminus. So when you put up your Syphon, aim it at your allies as well. With this, your ally can damage/heal/retreat freely and you gain charges for it.
5. Don't aim your Syphon forward.
Unless there's a projectile incoming or splash damage going off, never aim your Syphon forward. Your syphon also absorbs stuff from the side, so with this you can cover a larger area. Besides, people most likely won't aim at Terminus to begin with.
6. Time your swings.
Not much to be said here, only swing if you know you will hit. You swing every second, so make it count.
7. Retreat on time
Terminus lacks the skill to get out of combat quickly. Unlike some other tanks, he can't use an ability to get out or do his shield do all the work. Always keep an exit close to you, or save up some Syphon and charges to give you some more sustain.
8. Get the F in there
Don't be a wuss.
The best way to learn Terminus is by playing him a lot and noticing your own mistakes. There's not much to aim, but timing and your place on the field is what makes someone a good Terminus.
I hope this little guide helped everyone that wants to try Terminus or look for some tips. Good luck! :)
