That's pretty clever.
thought of it while i was fighting him with my snowman cannon with full ranged gear, first time finishing pillars i went to my town, saw the stuff and started pissing my pants, then he spawned and me not knowing any of his attacks or patterns i just shot anything with a health bar, found myself dropping in health really quickly and had to make regular trips to the nurse who was right under me, i won the fight but had to put in to much effort, and we all know you can't put any effort into anything ever.
And goddamn it feels good when everything falls perfectly into place, i get a good summoner build from accesories i saved and armor i made from the previous 2 fights, and just seeing that dragon doing billions of damage per second to everything while i stand perfectly still and click away is satisfying.
I am probably gonna be less cheap next time, gonna be a stubborn cunt and start a mage only run in an expert world, i can already see myself dying countless times.
