Overview
It is easy to use this hero if you are roamer or exp user with no mobility. I suggest flicker or sprint.His role is exp and tank, that's mean he is semi tank and he can be used for roam or exp.So, he can be used in both role in tank mode he needs to rotate in early like other tank (suggests:tank build) and he can be used for exp, he is good in damage so I suggest (fighter build)he is one of the most good hero in mobile legend.
Strengths
He farming is good in early his damage for creep and menion is good and he gain a lot of cc immune( every skill he used even his passive make him in cc immune)which make him to suggests tank build for protecting teammate when the enemy have cc and burst damage even in fighter build most of exp can't defeat cause of his cc immune and his burst damage.
Weaknesses
He is bad in movement speed which make him to rotate slow and even which made him slow in retreat.So, we need to carefully watch map cause he got no mobility if he got gang or ambush he can't retreat with his potential skill or which make him easy to feed early in early.
Tank and dmg
His movement speed doesn't good like other tank so I suggest movement speed build and tanky damage like thunder belt(up your stag in early for more damage and defence) and brute force make him to gain a lot of damage .So he is tanky speed and dmg.
Tanks and rotation
I choose those emblem cause he's movement speed is slow and he can gain high damage in early and in late game he can be tanky
Battle Spell
He doesn't have ang mobility skill so I suggest flicker
Before level 4 he is better to do not join in team fight .After level 4 he is strong in cc and cc immune so he can join in team fight
In level 4 he is better to camp in bush near the turtle area for vision and in team fight he needs to stay near a wall to stun enemy which make the stun duration little bit longer this make it the advantage highly of the team to win so he needs to stay near the wall.
Best With Badang
This hero need wall to give long duration stun so badang second skill can make wall, another advantage is they can be semi tank with many cc and cc immune. Which make the team fight more stable which can lead to victory
Watch Out For Hanabi
With her cc immune make her hard to attack for him also his high penetrated damage and her attack make him slowly and broke his defence lead to counter for him.
