Generally, use Detonate Plasma off cool-down too, though there might be a place where you want to delay it by 1-2 seconds, so sacrificed person on Matthias is freed. Or on Adina, when the main phase ends in like 1-2% of her hp, you might want to restrain and use it at the start of the Arm’s Phase.
The primary reason why you run so much boon duration is an ability to provide permanent Quickness uptime, high Resistance uptime, Stability stacks, Aegis spam, and maintain 25 stacks of Might with help of pre-stealing.
The ramp-up of your skills is not that fast, but it is carried with burst skills like Venoms, paired with spamming of Death Blossom and auto-attacks, but note that spamming any weapon skill (apart from auto-attacks) may make your character cast it twice or more, which will result in you being stuck in animations, lowering your dps.
Always ensure to use Detonate Plasma and Venoms after the boon strip that happens when you enter combat with the boss and don’t steal from Invulnerable enemies, as using Swipe will result in stealing nothing.
Be aware of the range of your Detonate Plasma (600 units around you) and Venoms (240 units around you) when applying them to your allies. Always position yourself, so you cover every one of them within the range of the aforementioned skills.
After your opener, keep using your initiative, try to maintain 15 stacks of Lead Attacks, when conditions from your Venoms and Preparation are active on the enemy.
Maintain Lotus Training uptime as highest as possible, and keep in mind that the buff does not stack.
Ritualist’s and Celestial gear is exchangeable, Ritualist will increase your damage slightly, and Celestial is just more hybridized (you also have to keep in mind, that by taking Celestial, you’ll have high toughness, so communicate with your tank to take more if you are not tanking.
Your second weapon set is situational as you won’t be using it for damage, you can pick whatever will suit your needs at a given moment:
Main-hand pistol for teleport backward and more range damage possibilities.
Dagger Storm is a potential damage option choice, especially, when you need to Dodge mechanics and while combined with Combo Fields, which you provide to yourself via Choking Gas.
In order to pre-steal on Adina, you can either trigger the boss and /gg, or you can use Swipe on the Earth Elemental that is blocking the passage to Adina’s area. If you have one stack of Detonate Plasma saved, when you are in the Arm phase in the encounter, by using Swipe on the Arm, you can get a second stack of Detonate Plasma, which helps to manage boons in the encounter.
In order to pre-steal on Mursaat Overseer, you can only politely ask your friendly squad to trigger the boss and write /gg.
On Twin Largos, you can either trigger the encounter, phase Nikare to get to Kenut’s platform, steal from her, and /gg, or you can use Swipe on the Dreg Shark that is blocking the portal to Twin Largos’ area.
