Daichi's Magical Water Bottle

Name: Water Bottle Plus
Type: Magical Container
Description:

Spoiler:

Strengths:
This is a magical water bottle that contains water. It doesn't really benefit normal mages that much, but for Daichi, a Water Dragon Slayer, this bottle gives him tons of benefits since Water Dragon Slayers get way more benefit from drinking water than your usual person. It can be used up to three times per thread, becoming empty once the user uses them all up.
Weaknesses:
Once the water bottle is empty, the user has to wait until the end of the topic in order to have it refilled once again. It can resist up to one C-rank attack. Once it is hit by something stronger, it loses its effectiveness and becomes an ordinary empty water container. The user can't manually refill this water bottle because its magical properties will vaporize the water due to the fact that ordinary water is different from the water gathered by this bottle. It doesn't allow the user to keep drinking the water in the bottle since it won't have any effect other than wasting one-third of the bottle's water. If the user stops to drink, he is left vulnerable to attacks since he focuses on that.
Abilities:

Name: Drink (This ability doesn't really have a name since Daichi simply drinks from the bottle without saying anything.)
Rank: C
Type: Water
Description:
The user opens the magical container, drinking one-third of the water inside. Usually, this ability will simply clench someone's thirst, but for Water Dragon Slayers, it grants them more than that. This ability will boost the user's vitality, increasing his strength and speed by 50%. With this buff active, the user can lift two times his own weight easily and run up to a maximum speed of 20m/s. When swimming, the user can move a faster speed of 25m/s.
Strengths:
This spell greatly increases both the user's strength and mobility, giving them a good increase in combat prowess. The user can also run faster than he usually can which might help when chasing or running away from someone. The user's ordinary punches deal C-rank damage due to his passively enhanced dragon slayer strength and the buff granted by this ability allowing him to easily take down weak enemies with just hand-to-hand combat.
Weaknesses:
This ability can only be ued three times per thread because of the water bottle's capacity. If the spell's duration is finished, the buff disappears. The user can't drink from the water bottle until its cooldown ends. If the opponent has a spell that can dry the user up or dehydrate him, the increase provided by this ability is negated. The user is left vulnerable while drinking so he can't just stop and drink when in a battle since he might be put in a disadvantage.
Duration/Cooldowns 3 post duration, 4 post cooldown. Can only be used 3 times per thread. Automatically refills once thread is done.

Cool-down of the spell needs to be higher, at least 4. Can't have you keep on drinking and keeping the buff all the time.
Also note that you are vulnerable while you stop to drink.

Bump. Edits made!

Approved.
