[PoE 3.23] Poet's Pen Frostblink of Wintry Blast Essence and boss rushing

Frostblink of Wintry Blast might be one of the strongest skills of 3.23, not only does it have unreasonably high damage, it is a movement skill so we can easily get HUGE amounts of cooldown recovery really easily in a way that puts all other spell trigger builds to shame. And being a movement skill, it lets us go FAST. Here's my interpretation on this build.

IMPORTANT: at least 153% cooldown recovery rate, and you can't go over 10.10 attack speed. for mana costs: inspiration in squire, militant faith, flask mana cost, ring mods, mana mastery as a last resort. pob: https://pobb.in/vh1Z0OIxTyyB atlas tree: https://poeplanner.com/a/8Wf

Notes:

1. Skill can double hit in the overlap. This is really important for damage especially on lower budgets - I showcase the insane damage of this skill by taking off 3 support gems (going down to 50M dps) and still easily oneshotting essence rares in a T16 map. In an earlier map with a tanky rare, I miss the double hit and it ends up surviving way longer. The easiest way to set up the double hit is to Frostblink in front of them and namelock the enemy.
2. The skill randomly misses triggers sometimes, I don't know why. Looking at my footage and that from other people playing this build, I suspect it is due to the minimum range of Frostblink and to a lesser extent server latency. So it's very important to aim for the 10.1aps, the 7.56aps version felt really clunky.
3. It's very easy to get stuck on walls, so mindlessly holding down frenzy maybe isn't the best move. Sometimes I also blink backwards for no reason. Open layouts are greatly preferred. I'm running Atoll because it's my favourite map, that's all.
4. During a gold rush, sell shovels. Thanks to the MFers ruining the economy, the prices of essences and invitations are through the roof. Based on my estimates with this strategy over the last few days, the average profit is about 20-25div/h. My guess for white tier essence farming would be about 15div/h, so still EXTREMELY lucrative if your build can't handle T16s yet.
5. You can actually go up to 15.15aps with Stampede, but honestly I'm already having trouble steering my character and 90% of my time spent in maps is clicking essences anyway. Here's a recent guide where the author presents a 15.15aps variant: https://www.youtube.com/watch?v=lX68F-1t4ek
