In my experience, the Red Iron Twinblade is a solid weapon in Dark Souls 2. It may not be as popular or widely used as some other weapons, but it definitely has its merits.
Firstly, one of the main advantages of the Red Iron Twinblade is its speed. Compared to Ultra Greatswords or heavier weapons, the Twinblade is much faster and allows for quicker attacks. This can be especially useful in situations where you need to be more agile and responsive, such as facing multiple enemies or in PvP encounters.
Another benefit is its lighter weight. The Red Iron Twinblade is not as heavy as some other weapons in its class, which means you can carry more equipment or invest in other stats without worrying too much about your equip load. This can be particularly helpful if you prefer a more versatile playstyle or if you want to experiment with different armor sets and accessories.
In terms of damage, the Red Iron Twinblade holds its own. While it may not have the same scaling or raw power as some of the Ultra Greatswords, it still deals a decent amount of damage. When upgraded and infused properly, it can be a formidable weapon that can take down enemies efficiently.
One aspect that I found to be quite effective with the Red Iron Twinblade is its poise-breaking capability. By equipping the stone ring, which boosts your poise damage, the Twinblade can stagger enemies quite effectively. This allows you to get in multiple hits on enemies before they can even respond, making it easier to dispatch them.
Of course, like any weapon, the Red Iron Twinblade may not suit everyone’s playstyle. It’s important to find a weapon that feels comfortable and enjoyable for you to use. However, based on my personal experiences, the Red Iron Twinblade is definitely a viable and effective choice in Dark Souls 2.
