The Samurai is a melee DPS class that has a lot of versatility due to it having both an AoE mobbing skill (Wild Swing, 2-handed sword only), a high damage single-target skill (Dual Slashes, 1-handed sword only), access to changing elements without changing its weapon (Fire, Water, Wind, and Earth Blade), and access to self-sustain (Heal Wounds). However, despite Samurai having all of these tools at their disposal, they don't have much in the way of SP at all early on. With that being the case, they don't play much different from other melee classes early on, and place more of a focus on AGI early as opposed to STR in order to flee their targets, especially if they're killing mobs one at a time.
Mobbing is plausible with Samurai, but it either costs a lot of zeny (potions to keep HP high, as you don't want to use SP for Heal Wounds with such a low SP pool), or you need to have already farmed cards that help with your sustain (Hell Poodle cards or Snowier cards). Another option is using various headgears and Ornaments (specifically Aegis with its +MaxSP enchantment) to increase your SP pool to be able to sustain yourself more, and use your offensive abilities more.
As a Samurai, you have two paths to choose from once you reach Job 40 or higher. You can either choose to be a Ronin, which is focused on speedy 1-handed sword techniques, or a Daimyo, which utilizes the strength and weight of 2-handed swords.
