I have enough of these treasure medals to get any of the lances and I'm not sure which one to get. I was curious what other lancers think. They are all 30 cost and have roughly the same stats.

Paradise spear: Chance to critical hit and heal your HP by 5,000 when using an Ability that inflicts physical or magic damage.

Blossom Lance: [Lancer-exclusive Skill] Chance to massively increase physical damage when using an Ability. Ability Power boosted by 30 when the target is in Break.

Assassin Spear: [Lancer-exclusive Skill] Ability Power 110. Damage 1 enemy with physical damage. Added effect: Ability Power boosted by 50 when the target's guard is broken. Combo effect: When used after Double Sting, Severe Sting, or Execution Spear, Ability Power increased to 120. Added effect: If target is already broken, Ability Power is increased by 50, increases your critical hit rate by 20% for 15 seconds.

Seems like either the assassin spear or blossom lance would be the better choice but I cant decide. At least the assassin spear looks cooler lol.
