Take in blood wyvns with high hp and melee your not gonna be riding them so stams not needed while they attack go on a land Dino with a shot gun

Bring a strong attacker but make sure it is a flyer

Did it no problem with 80k ho rexes and a velo ride the velo with friends in rexes and just whistle attach target when it lands

use blood crystal wyverns trust me

The queen is able to summon royal guard make sure you have two armour and stronger weapons to defeat the queen she has what is called the alpha call it summons alphas that target you.

Ok so this is gonna be a hard boss blood crystal wyverns are recommend a big dino to tank when you heal and a high hp dino so you can shoot of it back and not die so the boss dose 900 dange or more so you need High hp I tested a 275k hp griffin it dried in 24 mins by its self the blood crystal wyverns can mudder the boss so the wyverns need more than 13k hp so mutation is ok hp and dange and stanma is highly recommend med brews armor and level 100 level. No gigas

Take in a blood wyvern hp and speed

Bring in rexes. Set them to aggressive and let them attack the Queen while she is landed. Then, once in th flying stage, lead the rexes to the corner of the arena, the far back left. The Queen will follow, and become glitched in the corner, allowing you to easily attack her. Once she lands, just repeat the process.

My one blood wyvern Raum level 241 with 19000hp and 2410% damage killed it in 7 minutes
