League of Legends (LoL) Question: Nasus Support

1. As Prate_k said Spellthief's Edge
2. You go nasus support a poking support you should go first items Sorcerer's Shoes and Oblivion Orb so your E will do high damage as it have good high base damage, dont go Mikael's Blessing the item in bad state and you have 0 healing and shields i won't go even to Redemption. after the 2 Magic pen items, i would go into tank ( Frozen Heart Knight's Vow Locket of the Iron Solari Randuin's Omen and so on) or into AP with resistence/health stats.
for runes i would go Summon Aery as key stone (for better poke) and go into resolve ( Overgrowth Bone Plating)
3) A more burst like ADC would go good as Nasus do a lot of damage and can slow the enemy

Relic Shield 100%. First off, it's your tank item. It allows you to stack up your Q and your farm without actually hurting your support. Ofc, Nasus support isn't great because you can't take Nasus to his full potential unless he's getting 7 farm+ per minute (and if you do that as a support your ADC won't scale). I would use normal tank items but add in a support item or two, like Locket or Frozen Heart.

umm im not so sure about nasus support but if you want to you could do e q w r

I think that Spellthief's Edge is viable for poke, but Relic Shield lets you abuse the passive while stacking up more damage on your Siphoning Strike from the last hits you'll be getting. As a melee support, you'd likely want to run tanky runes, such as Bone Plating and Second Wind. Your primary tree should probably be Sorcery to give you access to Summon Aery. Champions that would pair well with Nasus support would most likely be poke-oriented champions such as Ezreal, or ones that can capitalize on your slow and burst them down such as Vayne or Varus.

Hope this was helpful!

I used to go nasus support in normal games more often than i should have in season 7

1) Spellthief's Edge
2) Resolve into Sorcery mana flow band and gathering storm. Items perhaps not extreme support items, because you need to last while tanking not keep your adc or team alive (i.e take all the damage) so after the wards, probably randuin's and abyssal but if you insist on a support item then zeke's probably. If you are ahead might as well try rylai's crystal scepter.
3) imo a long ranged adc, because you cant really protect them you just tank and spam w and e. Caitlyn/jhin but tristana might also work. because she can escape on her own.

Wenn ich in mein Arschloch 10 ghost-peppers stecken würde, würde mein anus dann verbrennen? Ich frag ja nur für ein Freund.
