Best Supports For Karthus Bot

• Nami - Nami's E works on Karthus' ultimate, providing a steroid and global slow.
• Senna - Good sustain and compliments Karthus with late-game scaling AD damage.
• Pyke - Always an excellent clean-up option to Karthus' massive AOE damage and also provides AD damage as a mix-up
• Ashe - Good sustained crowd-control and initiation abilities, also provides excellent kiting support

Karthus Bot Runes Setup

Primary: Dark Harvest, Taste of Blood, Eyeball Collection, Ultimate Hunter

Secondary: Presence of Mind, Last Stand

How It Works

Extremely High Sustained Damage

Although Karthus' early game can be mana intensive, as long as he has enough mana for his Q he can be extremely potent as a sustained damage dealer. He's also much less skillshot reliant than Ziggs, giving him additional room for error.

Excellent Combined with Reset Champions

The insane AOE damage Karthus provides works well with champions like Pyke as he brings the entire enemy team down low at the same time, even if he gets sniped out during team fights. This enables reset champions to make quick work of the remaining champions.

Potential Pitfalls

No Sustain

While marksmen can sustain a bit using Doran Blade, Karthus has no innate sustain and Doran Ring's healing will almost never come into play given Karthus' spammy playstyle. This means that without a sustain support like Nami or Senna, laning phase can be brutal against poke champions.

Low Survivability

Although Karthus has his wall to slow enemies to some extent, he's lacking in the utility department. Against many junglers he'll find it difficult to avoid getting caught out unless there's good ward coverage.

Countering Karthus Bot

Picking up strong all-in champions that can avoid getting kited and have your jungler camp his lane.

Karthus Bot Conclusions

This pick is much more viable than it has been in years past. Additionally, supports that work well with Karthus are very much in the meta right now, especially Nami who makes his ultimate a potential initiation spell.

Suggested Tier: Tier 2
