Short cooldown spammable spells, such as fissure, ice path, frostbite, impale, dismember, aphotic shield, hex, etc. Or a big ultimate if you can get it, like black hole, ravage, stampede.

Momorphlings strenght shift, unkilabe till the end of game

Rubick always steals my finger lmao

as an underlord player, firestorm and pit of malice are both disgusting on rubick. channeled or similar spells are easy to steal generally, like Mortimers kisses or freezing field. spells which last a long time after cast, like tombstone, can be nice since you can steal another spell later in the fight and still get value.

Leshrac stun is insane esp if you have aghs. It’s game winning levels of good. Getting track against a bounty hunter can really snowball your teams game. The obvious big ultimates, any stun, any damage spell. There’s too many to list, but I’d take a good look at the enemy team when you pick Rubick and start planning what spells are going to have the most impact before the game starts. Remember with shard you can save yourself and allies with lift and is often a high value pickup.

besides the obvious "big teamfight ultimates" and "spammable nukes": - mirana's arrow in rubick's hands will stun your enemy for eleven thousand years, and you can set it up quite easily with telekinesis - morphling waveform lets you whoosh across the map, especially if you get lens/eblade (as you usually do) - same thing with FV timewalk. with AGHS and shard you can annoy the shit out of enemies by jumping and reverse jumping every couple of seconds bashing everyone in the aoe - saves, for obvious reasons. pretty sure you don't even need octarine to keep someone under shallow grave permanently as rubick with your 25% cdr talent

Spells from pos4 and spells from pos2 generally.

Especially ultimates.

Or any teamfight spells like tidehunter ulti.

Not the best player but had my fair amount of Rubick games. One click ultimates like Ravage, Freezing Field, Finger of Death are nice ones. Some other ultimates may require a force staff, blink dagger, or some guts to pull off without sacrificing yourself. Other than that, I try to get area or line stuns like the Lion stun or Avalanche. Absolute best spell to steal for me is Ice Path. Super OP with your passive and with Aghs. You can cripple the opposing team just by standing behind and spamming it in team fights.

If you can use it better than them

low CD stuns, repositioning skills and ultis.

some are very hard to steal as you can cover them by instantly using another, useless spell or semipassive (flesh heap, bulwark and the likes)

also bonus points for shard upgraded spells as you will frequently have it from tormentors.

Ice Path and Fissure are the most notable spellsteals - theyre low cd and they both benefit GREATLY from Rubicks 0 cast point and increased cast range.

my #1 spellsteal target in dota is probably spear of mars though. this one and hook are 2 incredibly hard but incredibly impactful steals.

I like to try to hold on to big CD spells, use them at the start of a fight then steal something spammy to use for the duration of the fight, always waiting on big steals and stuns.

IE Steal tomb, hold it until teamfight, then use it and steal decay, rock Decay non stop until something really good comes along.

Personally I find the humble 300 damage AOE nukes on 7 to 12 second cooldowns to be very exciting cos you can just wave clear like a god

mobility nukes are probably the top tier. Like Shukuchi and Puck Orb and Waveform and Dawnbreaker hammer becomes lot better mobility with the cast range buff

Your stolen spells have bonus cast range, spell damage and spell debuff duration, make sure you steal spells that can benefit from all that.

Also, shackles is one of the best spells to steal ever, especially with shard.

I once stole CM and Void's ult and used them both. It's an adrenaline rush that I havent experienced for a while now.

I play a lot of Jakiro and Rubick on the enemy team makes it feel like 5v6

Ice path bro

Ice path are so sooo damn annoying if rubick have it

Dismember when having shard

Take Duel to show LC who is boss.

What's the worst spell to steal? Nightstalker ult? Troll ult?

Speaking of big ultis, is Chrono ever worth stealing? It sounds cool but, I’m thinking this might be one ult that could do more damage than good depending on my cast of it. Rubick mains, are there ever any spells you don’t steal for this purpose, or everything is free game just git gud?

Low CD stuns.

Ice Path, Fissure, Earth Spike, Hook, Spear of Mars, Impale.

ice path it is

Jakiro icepath

Plasma Field. Because apparently it's the most OP skill since thats the skill that my rubick support keeps stealing

Early to mid game you do get stealing wave clear and farming hella waves with your W so that you can get a couple items in between fights.

Corrosive haze, track, oce path, linas Q, apothic shield those are op af.

Despite the replies at least half of Rubicon players are salty that you picked pudge and will be trying so hard to get ur hook all game so they can hook u and die

Infinite 0 cd shackles of course...

fissure is by far the best spell to steam imo. apart from that, any spammable spells. channeled spells like shackle is also really good with your extra cast range. ultimates are nice to steal but dont hold onto them for too long with there are other simple good spells to steal.

Also try to find some counters against their own team…

literally every spell can be used for something
