Mesmers, it’s time we had a talk.
As you grow up, you’re going to notice your character is going through some changes. You’ll develop traits you never knew you had, and there will be skills you never thought to try. And once you start getting more comfortable with your newly found talents, you’re going to experience the urge to party. Don’t worry. This is perfectly normal.
I’m not here to tell you to abstain from partying. Quite the contrary; partying can be a very enjoyable experience between consenting players. It’s important to go in prepared, though. You need to have a conversation with your team to make sure everyone is comfortable. After all, there’s nothing more awkward than having one player blast your fire field while another is trying to give you a cleansing burst.
Developing synergy in your party is going to ensure you can slide into home base effortlessly. You want to make sure there is adequate access to condition removal (burning is not a desirable party outcome), and protect yourself by reflecting missiles that are trying to impregnate you. Talk with your party members about what your goals are, what you need to get the job done, and make sure everyone knows their role in that.
An example of this came up earlier when I posted my Mighty Jackpot Build that almost perfectly mirrored skcamow’s Chillruption variation. The difference is that skcamow’s build focuses on locking down enemies by chilling them where my build stacks might to share with the party. If I’m partying with two guardians who are each packing a staff though, I might find myself sitting in the corner instead of contributing to the fight. At that point, I’d be better off using skcamow’s build since might is covered.
As a Mesmer, we have a plethora of builds that can perform all kinds of tricks on the field. Fortunately, Fay has compiled a list of Mesmer builds and guides. Using this, you can increase your repertoire in the dungeon and be effective in any situation.
Just remember, communication is key to any party, and having a conversation before things get going hot and heavy will make for a rewarding experience.
Happy partying.
