I play AGI DW, and I would love to share my personal experience playing this character.
I love it... it was hard to learn alone playing with it, but keeping in mind that I am just a little "fish", and I have in game just about $400, I'm doing okay.
I will share my personal chain skill that I use in PVP. My chain skills are made with some help from ChatGPT. How did I manage to do that? That's a good question. Well... I work on a prompt for ChatGPT (took me almost 2 days to sort out that prompt), I write each skill with the description and what that skill do in different levels (that took me a full night and almost 1 litter of coffee), and to be honest, with the explanation from ChatGPT what the skills do and how to use it, I manage to build a skill chain for PVP.
Keep in mind that... those are my personal skills that I use in PVP, playing AGI DW.  

🧪 [1] Poison Spear
Why first? Guaranteed 2x hit for Death Poison stacks, strong AGI scaling, and high Death Poison chance.
Effect: Stack fast for Explosion and boost Curse synergy.

😈 [2] Curse
Why now? You’ll likely have Poison already active, extending Curse duration by +3 sec total (from Level 5).
Bonus: Roots target for 2 sec, +20% DMG taken – perfect timing for burst setup.

⚔️ [3] Poison Sensation
Why third? Buffs your Death Poison Activation (+25%), and grants ATK +3%, ATK SPD, and Skill DMG +200% when 3 stacks exist (which we ensured with Spear).
Combo: This power spike is critical before Poison Swarm and Explosion.

🕷 [4] Explosion
Why now? After you’ve stacked Poison + Curse, use Explosion to burst all DoT at once for lethal spike.
Bonus: Applies Death Poison boost, and benefits from Curse bonus DMG.

☣️ [5] Poison Swarm
Why now? A follow-up DoT zone to maintain Poison stacks and apply movement debuff (slow 30%).
Synergy: Prolongs pressure, maintains Death Poison triggers, and enables zoning.

❄️ [6] Ice Sealing
Why here? After DoT zone, freeze the opponent again to stop movement/escape.
Duration: With Mana Boost, freeze can last up to 2.5 seconds – long enough to prepare next move or reposition.

🌩 [7] Blizzard
Why now? Another potential freeze + slow. It buys time to regen or pressure. Also scales with ENE (you have moderate ENE).
Trigger chance: Can reset cooldown (15%) and applies zoning pressure.

🌀 [8] Switching
Why now? Reset your position, gain +80% DMG Reduction, or displace enemy mid-cast. Use as escape or bait breaker.
Cooldown is only 10s (after -5s reduction), so you can reuse it soon.

🫥 [9] Illusion (This skill, I use it manually)
Why last? Sustain and evasion buff if the fight drags or the opponent bursts back.
Bonus: Evasion +16%, 3–6% HP heal per dodge. Great for AGI builds.

I'm level 599, just about to turn T6 and this is my chain skills:
[1] Poison Spear  → [2] Curse  → [3] Poison Sensation  → [4] Explosion  → [5] Ice Sealing  → [6] Poison Swarm  → [7] Switching  → [8] Teleport  → [9] Illusion
And yes... I use in this chain Soul Barrier, Meteorite, Meteor, Grim Reaper's Eye.

That`all from my side. Thank you!
