The Barbarian, as a melee class without the ability to flash, requires understanding of the recommended skill combinations for a hero without flash if you want to play it well. After all, this is a powerful melee damage dealer, and only by reasonably utilizing and combining his various skills can you fully unleash the Barbarian's strength. His skills are quite complex and varied. Only by mastering different skill builds can you thoroughly unlock his potential.

1. Ice Hammer Control Build
If you usually prefer playing the Barbarian with a control build, then it's best to go for the Ice Hammer Control build. You can learn Ice Hammer Attack + Nimble Steps, along with Bul-Kathos' Power. Additionally, learning Ice Burst or Thunder can continuously trigger freezing effects through multi-hit damage, thus restricting the enemy's movement, making them unable to move.

Moreover, when freezing the opponent, additional damage will stack, and as the damage increases, you can further speed up your output, making the enemy immobile. This skill combination is also very effective in PvP, capable of directly interrupting the enemy's attacks or skills. In high-difficulty dungeons or arenas, it can produce surprising effects.

2. Bleeding Rend Build
Of course, if you don't like this slower-paced playstyle, you can use a more aggressive skill combination. It's recommended to use Rend, which causes continuous damage. Then, pair it with Rend again to further increase sustained output. You also need to learn War Cry and Ground Stomp, allowing you to continuously stomp on the opponent with rage.

You should also learn Frenzy, which increases your critical hit rate and burst damage. It's best to pair it with Bloodthirst, so you can recover health during combat, making you even more adrenalized. If you've learned Nimble Steps, you can dodge the enemy's attacks through agile movement.

To become a competent Barbarian, relying solely on brute force won't defeat your opponents. You can learn the recommended skill combinations for a hero without flash. If you want to follow different builds, you can learn various techniques based on the recommendations above. With proper combinations, you can utilize different abilities effectively, making you invincible.
