Ground Mounted Speed
All mounts in turtle wow have dynamic speed, the speed will adapt along with your riding skill. Below is a chart of how turtle handles the dynamic speed.
Every time you get on a ground mount without Riding skill the speed will scale with your level with the formula (Your Level * 0.5%). Example at level 30 you will have 15% mounted speed. The earliest mount you can get in turtle is the turtle mount listed here at level 18 you can start this quest.
Plainsrunning is a different story I still need a tauren to test for the speed percentage with Titanspeed. Rumors are that plainsrunning doesn't gain any speed benefit from mount speed items
Mounted Speed effects can be stacked just like in classic but there are 2 options in turtle that are upgrades or for a new slot of gear.
Enchant: Formula: Enchant Gloves - Riding Skill --> increases mount speed by 2%
Trinket Slot: Carrot on a Stick --> increases mount speed by 3%
Trinket Slot: Whip of Encouragement --> increases mount speed by 3%
Trinket Slot: Goblin Car Key --> increases mount speed by 3%
Trinket Slot: Gnome Car Key --> increases mount speed by 3%
Blacksmithing Spur: Thorium Spurs --> increases mount speed by 7%
Blacksmithing Spur: Mithril Spurs --> increases mount speed by 4%
Paladin Talent: Pursuit of Justice --> increases mount speed by 8%
Foot Slot: Boots of the Slime Path --> increases mount speed by 3%. Only mail users can use this boot slot.
Consumable: Aromatic Berries --> increases mount speed by 5% for 15 minutes.
Maxed Epic Riding Gear %: 125.22%
This speed is attained with Glove enchant, thorium spurs, boots of slime path, and both 3% trinkets.
Swim Speed
The turtle mount can be used to increase your base speed in water by 15%. Tested with Titanspeed. I always heard that the speed increase was 10% but this is not correct.
Swim gear can be stacked in turtle. Below is the gear that is available to use together.
Chest Slot: Captain's Overcoat --> increases swim speed by 15%
Waist Slot: Azure Silk Belt --> increases swim speed by 15%
Foot Slot: Deep Striders --> increases swim speed by 15%
Ring Slot: Ocean's Gaze --> increases swim speed by 15% you can wear two of these!
Trinket Slot: Ice Pearl of Kaneq'nuun --> increases swim speed by 15%
Trinket Slot: Hook of the Master Angler --> increases swim speed by 25% also gives underwater breathing
Trinket Slot: Rethress Tide Crest --> increases swim speed by 15%
Trinket Slot: Triskelion of Roving Elements --> increases swim speed by 8%
Idol Slot: Idol of Fluidity --> increases swim speed of Aquatic Form by 20%
Potion: Swim Speed Potion
--> increases swim speed by 100% for 20s (2min CD)
Potion: Fluidity Potion --> increases swim speed by 100% for 5 mins (2min CD). If you leave Balor all potions disappear from your inventory.
I am comparing the speed in water to mounted speed at 100%. Swimming in water for now is almost as fast as 100% mounted speed.
Swim Gear and Turtle Mounted Speed in Water %: 74.21%
Swim Gear/Turtle Mounted/Swim Speed Pot in Water %:107.94%
Swim Gear and Druid Swim Form in Water %: 86.01%
Swim Gear/Druid Swim Form/Swim Speed Pot in Water %:119.74%
Wyvern/Gryphon Flying Mounts
These mounts can be controlled and lasts for 45 seconds. An addon to track this turtle specific feature is listed here called FlyerTimer. This addon is dependent on BigWigs.
Swim gear modifies flying mount speed. I set my epic mount speed on titan speed to calibrate the titanspeed. This will eliminate the need to do the math when calibrating with running speed. The below values are what I got as a result.
Normal Speed %: 236%
Swim Speed Gear %: 271.53%
Swim Speed Gear + Swim Speed Pot %: 305.26%
Running Speed
Night elves get 1% movement speed buff. This changed in the turtle class changes that happened in 1.17.2
Running speed doesn't stack together!!!
Unlike other similar movement speed increasing effects, the movement speed granted by night elves racial additively stacks with other movement speed increasing effects. Night elf racial increases movement speed by 1%. Rogue Speed is increased by 7% and stacks with other movement increasing buffs.
Max Running Speed %: 110%
Back Peddle Speed %: 64.3%
Spell: Emerald Blessing
--> increases speed by 10% for all raid members within 80 yards.
