Lukas

The Main goal of the Build is to deal Ignis Damage while Renewal Puts you Back into Quick repost Range, the reason for +Def is more Ignis Damage, and With Summoner support and +Hp and the upgraded Lance puts you at 59 Hp

Merge: +0
Seal: Close Def 3

Enemy Phase Lukas

Positives:
+ Has amazing Def stat in which it allows him to take wide range of physical abuse before he finally falls
+ Also has great attacking power in which he can 1RKO his foes that dare attack him at close range
+ Ignis can often lead to powerful 1HKO's if he is allowed to do so
+ Can check a wide variety of Sword and Lance users, while he can check certain amount of Axe users

Negatives:
- Has non-existent Speed
- Also has abysmal Res which makes him an easy pickings for magic and Breath users

*clink* whats that sound? that's sound of 0x2 damage being taken. You won't be hearing that sound when lukas strikes back with a full 44 points of ignis damage and 38 base attack.

You probably won't even need him to tank greens, but he will tank them because he can. 0 damage from hector, 0 damage from amelia, 0 damage from brave ike, the list goes on.

New powercreep melee getting you down? Just use Lukas TM.
Warning: keep away from magic at all times.

(note: stats a +4 merge and summoner support)

Neutral stats are listed.

An arena build meant to maximize Lukas's ATK. Listed in order of importance.

B: Guard
This is non-negotiable. Lukas will be able to serve as a sort of mixed tank with high HP and DEF and passable RES against mages, so Moonbow procs will be very dangerous for him.

IVs: +ATK/-SPD
Foes who are susceptible to Distant Counter (mages) generally have low HP and DEF. An ATK boon combined with Distant Counter will give Lukas the highest chance of one-shotting mages who would otherwise cripple him due to his low SPD and RES. Any bane is fine with RES probably being the worst due to it being a -4 bane. A DEF bane can be covered with a weapon forge +DEF for a net gain of +1 DEF. An HP bane will help Lukas play the role of mixed tank by leaving his DEF and RES untouched. W!Tharja makes a case against a SPD bane because Lukas will has 4 more SPD than W!Tharja when both are at neutral SPD. This increases to 6 SPD on the enemy phase due to Tannenboom!'s effect. This means Lukas will be able to double W!Tharja on the Distant Counter naturally.

A: Distant Counter
As mentioned above, this is to combat mages. With Distant Counter, Lukas actually ends up winning the red mage matchup and can one-shot a sizeable chunk of the relevant blue mages. Lukas will also be able to retaliate against bows like B!Cordelia, taking minimal damage from her Brave LaD builds and one-shotting her on the counter.

Weapon: Tannenboom! +RES
Tannenboom! was tailor-made for Lukas. Lukas functions best as an enemy phase unit so he can take advantage of his ridiculous DEF. Tannenboom! comes with the added benefit of +2 to his ATK, DEF, and RES, all of which are stats he needs to function as an enemy phase wall. RES is the recommended forge because Lukas will have so much DEF against ranged that a DEF forge will yield diminishing returns. A DEF forge can be used if his IVs are +ATK/-DEF. This is slightly more optimal than using a RES forge with +ATK/-RES.

Seal: Distant DEF 3
This is mostly used for B!Lyn and mages. Distant DEF has insane synergy with Distant Counter, as Lukas will be able to reduce damage from mages while one-shotting them with Distant Counter.

The next three skills are more flexible.

Special: Galeforce
This is mostly to check Brave Bow Lyn builds. She will quad on the enemy phase, and Lukas will be able to run in, one-shot her, proc Galeforce, and run back to safety. Galeforce charge isn't limited to Brave Bow Lyn, as Lukas can use anything he's walling out to charge his special. This also somewhat makes up for Lukas's nearly-nonexistent SPD and lack of Quick Riposte, as he will be able to take two turns of combat during the player phase. This can be swapped for Ignis if Lukas needs to win matchups with triangle disadvantage.

C: Panic Ploy
Panic Ploy is chosen to inhibit Emblem teams from setting up buffs. With a forge, a neutral Lukas will sit at 50 HP. This is more than enough to warrant using an HP based skill. However, the C skill can be tailored to you team's needs as always.

Support: Reciprocal Aid
Similar rationale to Panic Ploy on C. Lukas has enough HP to act as a one-time healer in case there's nothing for him to wall out. Conversely, if Lukas sustains too much damage and falls out of Guard range, he can use Reciprocal Aid to heal himself back up. This will require running someone with a decent HP pool to act as support. As with the C skill, this can be substituted for a movement skill or a rally, depending on what your team needs.

Stats:
45/35/22/38/17 (neutral)
45/38/19/38/17 (+ATK/-SPD)
45/52/19/38/17 (Tannenboom!+)
50/52/19/38/21 (RES forge)
50/54/21/40/23 (Tannenboom!'s effect on enemy phase)
50/54/21/46/29 (Distant DEF's effect against ranged on enemy phase)

Lukas is one of the strongest physically defensive infantry walls, Slayign Lance+ with a +def upgrade and +3 defense SS puts his defense stat to 53, making it virtually impossible to knock him out even with the strongest axe hero. The opponent must take caution too, as if Lukas proc's Ignis it could mean certain death.
