Hello!
Little tutorial for Dragon Lord Refuge since many people ask to join my premades but i rarely have spots, so you can try the instance by yourself 
-----------------------------------------------
What is DLR/TH:
- Instance of 12 people in the middle of tiamaranta's eye
- Drop extendable weapon, nice weapon and wings skin, decoration but more importantly mithrils QQ (+ around 50 kahruns per run)
- 3 differents phases: Calindi, incarnations, Tiamat
What do i need for the instance:
- One templar and one support (chanter prefered) with a magic resist gear (around 2k3 with food)
- One good leader who has to announce all the calls in tiamat, everyone on voice chat
- At least one ranger dps, 2 prefered
- Good dps overall
- 2 clerics and 2 chanters support.
- Elemental scrolls fire and earth
----------------------------------------------
Calindi:
The templar pull the boss to the left or the right side. When the boss casts hallucinatory Victory, Everyone stops DPS becauses the boss will has a reflect (lead announces it). The range dps kill the surkana as fast as possible. Once you see that the reflect buff is out, you dps again. Other than that the boss isn't complicated at all but hits hard on the tank.
Incarnations:
Nothing hard. Grp 1 take the 2 doors on the left, grp 2 the 2 on the right. One chanter buffs Kasinel (or Marchutan i guess). Kill the incarnations and regroup fast next to tiamat once it's done.
----------------------------------------------
Tiamat:
Here things become a little bit complicated if it's your first time.
- The first phase is pretty easy, dps until 51%. Range dps stay in range with supports and try to avoid the cast of atrocity (staying on the spot at the beginning of the video). Don't use dp or huge cds
- When the boss has 51%, Stop dps, this is really important because once spikes are up, it begins a timer of 1:15 min where depending of the life of the boss, something will happen.
- Everyone wait with the range dps the spikes: Time to put your elemental scrolls back and switch gear for templar/chanter. Spikes will be up after the boss cast atrocity on the left side.
- When spikes come, the leader begins the timer. Chanter uses WOW. Once the boss casts atrocity another time, you can begin to dps.
Things depend of your premate: If you have a very good dps, you will have to stop at 26% before adds come (after the next spike which is at 1:15). If you haven't, the premate dps until the end. If you don't stop the dps at 26%, you will take the stun in 30s which is super bad.
Adds come at 1:15 - 2:00 - 2:45. Mass and very dangerous stun comes at 2:55. The leader needs to announces all those waves 10s before.
- 10s before first wave (1:05). The templar takes the right side and the chanter the left one
- First waves (1:15). the second chanter switch on distant group and use speed cast, then reswitch on the melee group. Glad uses dp. It's the moment to dps hard! Templar takes his 2 adds on the right and comes take the 2 adds the chanter aggro on the left.
- 10s before second wave (1:50). Chanter and templar come back to their respective spot (templar already have the 4 adds).
- Second wave (2:00). Templar uses iron skin and taunt aoe to take his adds, then join the chanter and heal on him to get all the mobs. Chanter uses elemental screen
- (10s second before 3rd wave (2:35). Templar and chanter to their respective spot, clerics need to use 4k dp)
- (3rd wave take the adds blabla... get ready for mass stun, announce at 2:45 10s before it and try to finish the boss fast cuz it will become way harder if the stun comes).
I think it's a little bit more illustrated with a video so here we go
--------------------------------------------------------
Then enjoy your mithril kappa (or your exten weap if you are crazy lucky)
