Arachne Season 7 Duel Guide

In every game you should buy items fast and place 2 spiders on the speed buff, than back to get full mana and kill the buff without wasting abilities on it. Most of the gods in the game have better clear, so you should double buff but still don't waste time because you don't want to miss any of the first wave. After that if there's no special conditions you should be passive until you get to 700 gold and than you back for full Golden Blade.

Against an auto-attack based god:

If you plan your attack after he uses his abilities and before level 5, you should be able to kill him in the second wave of minions. Throw spiders at him between the waves to make him use potions or abilities. Don't be too focused on getting the red buff just try not dying in the first 5-7 minutes of the game.

Against an ability based god:

For the early game you should really just be aware of his cooldowns and mana and if they are down, you should engage and chase the kill but save your ult for escaping unless you're 100% sure you'll get the kill. If the first blood drops early for you, don't be scared of dying and engage more frequently but still be aware of his cooldowns especially.

Against a tanky god (Warrior/Guardian):

Here you should just focus on farm from the first second. You should just be patient and wait for the right moment to engage, if not, he'll definitely engage, because you win mid and late game.

Now you should be full built with core items and your kill potential gets higher. You're now playing the farm game, getting yours and occasionally his camps. Also if you destroy his tower, you should get the Bull Demon. You burst it down really quickly and if you know your opponents location and it's not close to the Bull Demon there's no chance of catching you.

Against an auto-attack based god

Try to make him fight the wave without his minions and burst him down, but don't chase if he's faster than you and you're on cooldown. Don't rely on Serrated Edge too much. Remember to keep your ult for escaping and be aware of his and yours relics cooldowns.

Against an ability based god

Here it's the same as early game, just remember to watch his build and know if cooldowns are lower. Overall you should be really vigilant, because the slightest slip off means death in most of the cases. Don't try to out-damage him with his abilities, unless your way in front.

Against a tanky god (Warrior/Guardian)

You should definitely build some defense against a warrior. Mid game is where it gets better for you, if you have been surviving early game and you're not too far behind. Now you deal significantly more damage and he doesn't. Still, you should be careful and make him engage if you can.

That's your best game. With full build and/or 20 level there's almost no chance of losing the game, if you play your cards right.
Now there's no difference in which type of god your fighting because you have one job only - burst him down. You should not be scared of engagements even on towers/phoenixes, of course don't dive if he's full health or have ult/stun/relics.
