Overview

Jamal is the SR Heavy Tactical damage slot, the opposite of Hank. Nail Gun ticks every 1.55s. Quick Repair is a dual-pistol spike barrage on the front 2, 10.3s cooldown, not a heal. Survival Expert unlocks at level 31 and 4★: 5% ATK, DEF, and HP. The live roster has 3 SRs; he is the attack one.

At Lv.150 / 5★ he has 233,554 HP and 13,091 attack. Attack is first of the three: 13,091, then Jackson 12,829, then Hank 7,593. HP is last, less than half of Hank (498,368). Summon: 10 fragments.

Best for / not for

Pick him when the SR damage slot is empty and the march can be Tactical. 13,091 attack is first of the 3 SRs, and Nail Gun is 1.55s. Pair him with a real front (Hank, later Arnold) rather than replacing one.

Team

No ally line in the kit. Quick Repair hits the front 2 enemies, so he wants two bodies in the enemy front. 233,554 HP is not a front; put Hank, Arnold, Dirk, Toxina, or Zara there. Same-army Heavy Tactical names: Arnold, Dirk, Toxina, Zara, Hank. Keep Hank on the line if both SRs are in the march.

Investment

Skill books are the sum of the per-level costs in the game data. Use the hero calculator for EXP and fragments.

Skill	Books to Lv.30	Books to Lv.40
Nail Gun	176,730	176,730
Quick Repair	176,730	176,730
Survival Expert	176,730	176,730

Nail Gun first: 1.55s uptime is the kit, 292.76% ATK at 5★. Quick Repair second: front two at 653.1612% ATK. Survival Expert third, when it unlocks at level 31 and 4★: 5% on 233,554 HP. Books to Lv.30 and Lv.40 are the same 176,730; do not plan a 40 dump.

Verdict

Jamal is the SR nail gun, not a tank and not a support. Use the 13,091 attack and the 1.55s cooldown, keep him off the front, and retire him when a fuller Tactical kit (Toxina, Zara, Arnold) is ready. Survival Expert is worth the 4★ if he is still in the march. Do not raise both him and Jackson to 5★.
