How to play The Morrigan in Smite 2!
The Morrigan is a god whose complexity mostly comes from their ultimate. Her base kit isn't too hard to understand. She is a threat the moment she reaches level 5. Being able to turn into anyone is extremely threatening and allows for some game-winning plays. For The Morrigan, you want to build accordingly to what the enemy team has of course, but CD is extremely important so you can have your ult up as much as possible.
The Morrigan's main combo is 1-2. Her 1 is a short-range stun that can be surprisingly hard to hit if the enemy knows it is coming, so be sure to focus up when trying to hit this ability. Her 2 is a long-range wave that is good for poking and wave clear. Her 3 is a good ability for ambushing and escaping as it makes a decoy and makes her invisible. The Morrigan's ultimate allows her to switch into any god that is in the match. Pro tip, you can hover over a god's portrait when activating the ult, even without having the ultimate yet pre-level 5 to have a god ready to pick when casting. This is useful so you don't spend a long time picking a god for a situation that arises.
The Morrigan also has an aspect that will change how her 3rd ability will work. Instead of going invisible when sending out a decoy, she can instead swap locations with it. This does make ambushes harder for her but allows for really crazy plays and baits. Choose this aspect if you feel like a more trickster playstyle is what you want. Be aware that you are easier to catch in some cases though.
The Morrigan should be positioning in the backline in teamfights so she can widdle down the enemy team with her 2. She can peel and self-peel with her 1 but it's risky to get that close in teamfights so you should try to save it for when your team engages, or you get engaged upon.
Ganking and rotating with The Morrigan is something you should try to when playing her in the Middle Lane. Her ultimate allows for nearly an infinite number of plays when ganking, and it's up to you to decide what the best god to copy is for a gank. The Morrigan can also be played in the jungle but does suffer from a weak early game. She is susceptible to being invaded early, so don't be afraid to ask your team for help.
Generally, turning into a tank is a safe play for The Morrigan. It allows her to go in and be hard to kill for her team while disrupting the enemy team with double to CC or damage that she will copy. It also allows for easier time escaping sometimes depending which tank you choose. The best targets to switch into for The Morrigan will almost always be the most fed god in the match. Being able to take the player who has a whole item lead's form can be great for catching your team back up in a gank or objective.
Here is a general build example for The Morrigan
Sands of time: Her clear will be a bit worse in the early game, but the CD and mana on this item will be very valuable. The upgrade to this item also allows for even more CD and a nice passive for building mana.
Book of Thoth: This item helps a lot with damage once you get it stacks. You will lack damage before this item gets built though so plan accordingly when preparing to attack.
Chronos Pendant: The Morrigan loves CD and I believe this is one of the best CD items in the game with an extremely strong passive and a lot of CD with a fair amount of int.
Spear of Desolation: This item has a lot of int and some pen with a passive that I think works amazingly with The Morrigan. Having that CD reduction on a god kill can really allow you to escape or get even more kills after going in.
The World Stone: Reducing the CD of your ultimate for someone like The Morrigan is game changing. This item also has nice stats and is overall a must have for The Morrigan.
The Cosmic Horror: CD is important for The Morrigan, and this item gives a lot of int and CD.
Rod of Tahuti: Finally, this item gives you additional int which helps with The Morrigan's damage outside of ultimate form.
Other Situational Items:
Divine Ruin is a good anti-heal option for when the enemy team has a lot of healing, such as from Hercules, Anubis, and Mordred
Obsidian Shard is a good item against tanks if they are a huge threat during your match.
Soul Reaver fills the same niche as obsidian shard and are typically built together. Soul Reaver is more important though if you only want one anti-tank item.
Polynomicon is a good option for The Morrigan if they lack tankiness on the enemy team. That auto in-between her 1-2 combo can straight up kill an enemy god. Doesn't work so well against tanks so I would avoid this if tanks are a big threat on the enemy team.
Overall, The Morrigan can be hard for someone interested in learning her, but as you continue playing you will begin to understand which characters are more of a priority to switch into and which are less likely to be useful. It takes time but it is definitely worth knowing how to use all gods kit at a least basic level as well.
