Situation:
Player 1's Sangan attacks Player 2's Lightsworn Paladin Jean.
During damage calculation, Player 1 activate Prideful Roar,
Player 2 chain Honest.


Prideful Roar:
戦闘ダメージ計算時、自分のモンスターの攻撃力が相手モンスターより低い場合、その攻撃力の差分のライフポイントを払って発動する。ダメージ計算時のみ、自分のモンスターの攻撃力は相手モンスターとの攻撃力の差の数値＋３００ポイントアップする。
Activate only during damage calculation when the ATK of your battling monster is lower than the ATK of your opponent's, and pay Life Points equal to the difference in ATK. Your monster gains ATK equal to that difference +300 during damage calculation only.

Question:
1.How does the chain resolve?
2.How many LP does Player 1 need to pay?

Answer:
C1尊嚴的咆哮(此時已支付攻擊力差距為800的LP)
C2誠實處理1.誠實為聖騎士增加1000點(三眼怪當時的數值)攻擊力
2. 尊嚴的咆哮為三眼怪增加差距為1800點+300點的攻擊力結果, 攻擊力為3100的三眼怪與攻擊力為2800點的聖騎士進行戰鬥

Translated by Akira:
Chain 1: Prideful Roar (800LP paid as the activation cost)
Chain 2: HonestResolve1. Honest's effect increases Lightsworn Paladin Jean's ATK by 1000 (The ATK of Sangan at this moment).
2. Prideful Roar's effect increases Sangan's ATK by 1800 + 300.As a result, Sangan with ATK 3100 and Lightsworn Paladin Jean with ATK 2800 will conduct battle.
