it isn't even that long bro
Time's valuable, the 20 minutes that I saved by not clicking that video could be spent doing something productive, like grinding on Touhou 19 to unlock more characters.
would this be done at the start of the match or after getting hit?
Well, The Terrarian doesn't have a personality, nor we know how he thinks. He is just a self insert of the player, he wears what the player wants him to wear. But if we go by what Terraria players usually wear in the end game, there's a high chance that he starts by wearing that armor.
The loadouts mechanic makes this even more likely, since with that system he has multiple choices of accessories and armors that he can switch to when the player presses F1, F2 or F3.
But even assuming he doesn't start with that armor, or that they're not in his loadouts (Unlikely since most keep loadouts based on different classes), he could simply grab it out of his inventories and change armors in seconds.
The same thing about summons and sentries can be applied to the Stardust guardian. Nothing in the game can kill him, not even enemies that can one shot The Terrarian. They're invulnerable to every attack in the game. Though I am not sure how that would work in vs matches.
assuming that's something that is somewhat close-mid range, Akiha would look at him and his life is drained.
what are the ranges on these?
yes, but what happens when he gets too close and hair spawns on his body and drains his body heat and life force?
Assuming The Terrarian starts with a close-ranged strategy (It's unlikely but possible, he doesn't have standard strategies) and he sees that his life is being drained. He will use the Rod of Harmony to teleport away from Akiha and switch to a long-ranged strategy.
But if The Terrarian starts with a long-ranged strategy, (Which is the most likely scenario because in Terraria even melee weapons can shoot projectiles that travel tens of meters or his max range) it's even likelier that he will completely avoid being touched by Akiha's hairs.
That being said, the flamethrowers, Solar eruption and Daybreak have a range of tens of meters. That being said, it's likely that he will use these weapons offensively to defend himself from Akiha's hairs while they're trying to grab him when he starts taking distance.
Here's what will happen, The Terrarian flies and teleports away to gain more distance and outrange her. His minions, sentries, long ranged weapons will attack from a large distance while The Terrarian uses fire or daybreak debuff inducing weapons to incinerate any hair that gets close to him.
that's what happened in the thing I sent. Akiha was on the floor above and her hair was going through floor, and just kind of moves around the air like blood vessels.
The Terrarian will dodge and incinerate any piece of hair that gets close to him. The Inferno potion and his fire weapons makes it so that Akiha's hair will burn when they get close to The Terrarian.
Edit: Adding something very important that I just saw on her profile.
You need to be able to see spirit/ghost stuff in order to see and interact with her hair.
Well, The Terrarian's profile say that he can physically interact with souls, wraiths and ghosts. He can even use souls as crafting materials. He would be perfectly capable of interacting and seeing Akiha's hairs, since he can touch and see souls and similar spiritual beings.
The Terrarian also has the Lightning Aura staff
https://terraria.wiki.gg/wiki/Lightning_Aura_sentry_summons which summons an aura of lightning that passively damage everything inside of it. He can use it to defend himself against the hair.
I should also mention that The Terrarian has weapons that are worse than his end game weapons but are items that control fire and have the maximum range of The Terrarian. The Fire Gauntlet
https://terraria.wiki.gg/wiki/Fire_Gauntlet for example, makes all of his melee weapons like the Zenith inflict the Hellfire debuff which is stronger than normal fire.
He can also use Cursed bullets
https://terraria.wiki.gg/wiki/Cursed_Bullet or Cursed arrows on his long distance ranged guns and bows which are munition that inflict the Cursed fire debuff, fire even stronger than fire and helfire that cannot be extinguished with water.
