Usage

General

Every elixir skill (including toolbelt ones) can proc extra 中毒 from 瓦思古物.
- Using elixirs with a cast time in the middle of burst combos tends to be a DPS loss. Either build up some stacks beforehand or simply use your skills as intended without stressing over the procs, you'll still have good 中毒 uptime without having to think about it too much. Think more about how you're going to consume the procs you end up with.
Your elite skill 空投补给 can be used both defensively and offensively, although it's best saved as a defensive utility. Once there is too much pressure to handle use the 释放烟幕 from 烈焰炮台 to 潜行 for long durations and quickly escape unfavourable situations. To consistently trigger 释放烟幕, use any skill while having an active target within 500 range of the 烈焰炮台. It's recommended that you only use this skill offensively in desperate situations, as to not leave yourself vulnerable later on.

Damage

Spear has a central mechanic called focus. Focused targets are more heavily affected by your Spear skills.
You make someone your focus target by hitting them with 管流激增. Using this as your opener is therefore recommended.
Skill #3 闪电矛杖 should be activated as soon as you use Conduit Surge. It's an instant skill that does damage passively around you and being charging up its chain skill.
- Charging it up turns this skill into 电气炮轰, a long range strike with Immobilize Immobilize, making it great at setting up burst.
连绵起伏 is primarily a setup skill too as it's a CC with not much else to it.
毁天灭地 is your primary burst skill on Spear. Try to land it on focused targets, preferably when they're CC'd so it doesn't miss.
The toolbelt skill 手雷弹幕 is your other big burst skill. Both this and Devastator are great at consuming Vass stacks too.
Spam grenades when your Spear skill are on CC or if getting into melee would be too dangerous. Fill any downtime with grande spam, even if it's just the autoattack.
手雷包 skills ranked from most to least threatening:
- 破片手雷. Simple fire and forget skill with great damage.
- 毒气手雷 and 冰冻手雷. Poison Grenade does more damage over time and it's unblockable, which is important because you can even use it to score healing reduction on skills like Revenant's 水晶休眠, but Freeze Grenade does more damage upfront so it's better for bursts.
- 闪光手雷 does very low damage and is mostly a defensive tool that 目盲s enemies, but it's still good for condi variety and proccing traits too.
Even your healing skill is a minor source of burst damage in melee range:
- H型试剂 procs another elixir via trait synergy, granting you a total of 6 瓦思古物 procs. Using a healing skill also triggers a lesser 手雷弹幕 around you from traits, which could immediately consume the Vass stacks you've just built.
- This is quite useful for counterpressuring targets, sometimes even turning the tides against the one chasing you. Be warned though that the grenade proc could also end up accidentally breaking your 潜行 when you heal next to an enemy, which could actually endanger you on low health.

Sustain

Elixir skills remove conditions, providing a steady stream of cleansing in combat.
Your healing skill cleanses multiple conditions because it also procs 逆向转化.
医疗空投 is the closest thing you've got to a mass cleanse, although it's not as simple as just pressing the button - you have to pick up the Med Packs by walking over them.
- If you're really pressured you could follow this up with S型试剂. Being invulnerable makes it much easier to pick up the Med Packs, and the invuln also makes you stop taking condition damage while you grab the cleansing you need.
S型试剂 is your time out button, use it to avoid burst damage if there's no other way out, or to extend your life at low HP. It also breaks stuns.
气流爆破 is your fast but short cooldown CC, you can use this to knock away hostiles chasing you. This skill also doubles as a projecitle reflect, working both infront of and behind you.
U型试剂 is your other stunbreak, but as long as Elixir S is available you're free to use this skill offensively too for the 急速.
Toolbelt elixirs are also quite useful - 投掷H型试剂 can give you 保护 while 投掷U型试剂 grants 奔驰疾速 which is great for kiting enemies.
- The superspeed works even better when combined with skills that snare enemies, like 冰冻手雷 or 电气炮轰.
Spear offers very little in terms of sustain, but at least 管流激增 and 毁天灭地 are mobility skills which you could use to quickly build some distance.
