Several times each century, the clockwork plane of Mechanus mobilizes a vast wave of modrons and sends them on a tour of the cosmos. Known as "The Great Modron March", this unstoppable tide of lawful constructs journeys across the material plane on the exact same route each time. However, this time something has changed -- the modrons are marching on Waterdeep.
The Great Modron March returns once again, and while the many constructs of Mechanus march upon Waterdeep, the latest new Champion arrives: Vlithryn, Cleric of Persana!
Keen eyes may recognize Vlithryn - and her banshee-like scream - from the web series 1 For All, where she is played by the amazing Soylent Cosplay. Vlithryn is the first Featured Champion for Great Modron March this year.
The second Featured Champion for Great Modron March 8, Yorven Springpaw, arrives next week on May 14. Players will be able to learn all about Yorven's changes in the Yorven Champion Update blog on Friday, May 9th.
For more information about this year's event, read on!
Our intent for the Boon XP Augment is to amp up the rewards for players who choose to purchase items that grant event boons. While the pricing of each boon level differs from the standard system, the rewards are greatly increased. This ultimately yields a substantial overall increase in the power of the buffs players gain for each platinum they spend on event packs. Here is a comparison of boon levels in the standard system vs the Boon XP Augment.
* Note: We have tweaked the Click Damage buff in May as noted above.

Featured Champions
Vlithryn

Ever since she was a hatchling in her kingdom under the sea, Vlithryn has dreamt of helping the less fortunate land dwellers and spreading the good word of her God, Persana. She’s always willing to lend a helping hand, or a healing word, to those who need it, for the right price, of course. She is usually cool, calm, and collected, but don’t get on her bad side, or her banshee scream and lightning attacks will leave you begging for a revivify that you can’t afford.
Learn more about Vlithryn in her Champion Spotlight.
Yorven

When Yorven came across the Witchlight Carnival, he managed to convince the owners to bring him on board. When the Witchlight Carnival returned to the Feywild years later, Yorven moved on, seeking his childhood home - and the hags who banished him.
Learn more about Yorven when his spotlight releases next week on May 9th!

Boon XP & Boon Level Changes
As always, your feedback is incredibly important to us. Since announcing the return of Boon XP as an Augment last week, we've heard concerns that your platinum does not go as far when this augment is active compared to the standard boon system. We'd like to provide some additional clarity to show the increased rewards between the Boon XP Augment and the standard boon system.Our intent for the Boon XP Augment is to amp up the rewards for players who choose to purchase items that grant event boons. While the pricing of each boon level differs from the standard system, the rewards are greatly increased. This ultimately yields a substantial overall increase in the power of the buffs players gain for each platinum they spend on event packs. Here is a comparison of boon levels in the standard system vs the Boon XP Augment.
