INN AT THE EDGE OF TIME
PRIORITY LIST
I personally would recommend you be level 90, a doom knight, have defender's gear maxed, and have 600 dragon points before attempting most of these fights. In other words, sit out two years until you are eligible for Doom Knight and you can train your dragon with free food (the dragon coin food adds up!) Some fights are very challenging. Not necessarily these first seven sets I recommend (the eighth maybe), but others are. These are the classes I recommend highest to complete these fights with. I generally use 200 protection, 200 assistance, 200 mischief for my dragon. Armors do not need to be in inventory, they can be banked if they are purchased armors. Just make sure you possess an Armor Closet in order to change between them! I highly recommend stat-enhancing food (costs 1 Defender's Medal) and 5 of each potion (costs 2,000 gold, 2,500 if you get the potion dispenser machine for your house, which is more convenient than having to travel to the Neiboheim market every time. Pretty simple, if your main stat is DEX, use Raven's Wings, if INT, use Baked Basilisk.
#1
Undead Duo (you only need to complete the duo)
I'd do this fight first so you can grab the bracer, it's easy anyway. Stats are 200 DEX, 200 END, 45 WIS. Assuming you're just starting, so your gear is probably very basic, hopefully you have this...
#2 (part of)
Elemental Chaos (plus both Theano and Siofra)
This is an easy fight, you should be able to obtain it early on. Good to get your light weapon ASAP! Stats here are 200 DEX, 200 END, 45 WIS. I am assuming you do NOT have any top-tier weapons at this stage, so I'm recommending the DDASoE, plus it's versatile here.
#3 (part of)
Triple Trouble (you only need to complete the trio)
This one is likewise an easy fight, and is also needed for your light weapon. Again, 200 DEX, 200 END, 45 WIS. Again, you probably aren't geared well at this stage, so the DDASoE is adequate for this fight. This is a great time to use your Dragon Knight set for an additional 75% damage to dragons!
#4
Crystal and Stone (as well as Rictorild in addition, do NOT need to complete solo Roktoru)
This one is moderately challenging, but not horrible. Stats are 200 DEX, 200 END, 45 WIS. It is useful for future battles to weaken enemies against light, such as the Challenger Gauntlet, to make it faster. Especially since you're going to be doing it 15 times.
#5
challenger Gauntlet
You will need to complete this 5 times per main stat you desire a belt for! Hopefully, you've obtained your Ultimate Twin Blades of Destiny by now. Stats are 200 INT, 200 END, 45 WIS. Weaken Verylrus against light with Summon Vizalain with the Summon Gem - Ricteirild.
#6
Zeklem's Keep
Fighting the boss is not mandatory here, just need to deal with trash and occasional mimics. Objective here is treasure chests to claim relics to upgrade your Unhallowed death knight gear. Stats are 200 INT, 200 END, 45 WIS.
#7
Exaltia Tower
Now to get your good / evil weapon, which is largely your all purpose weapon. You will grind it in the Exaltia Tower, which will be in five phases.
Ezrajal / Yaphael
Easy boss. Should not be any issue. Stats are 200 INT, 200 END, 45 WIS.
Couerihem
Slightly more difficult. Mostly collect schism runes along the way. Stats are 200 DEX, 200 END, 45 WIS.
Warden
Not too bad, this one is fairly easy as well. Stats are 200 INT, 200 END, 45 WIS.
Daatael
First actually challenging boss. Mostly an endurance battle. Stats are 200 DEX, 200 END, 45 WIS.
Engineer
This one is the most challenging boss you've faced so far...if you don't set it up right and aren't slightly lucky. There is a strategy that works half or so of the time with chaosweaver. It depends on stunning him just right. I'm linking a video someone else did of said strategy. Stats are 200 INT, 200 END, 45 WIS.
