What is mhw guard up?

MHW Guard Up is a skill in the video game Monster Hunter World that allows players to guard against attacks that would normally be unblockable. This skill allows players to use their shield to protect themselves from attacks that would otherwise cause them to stagger or knock back. Guard Up works particularly well against heavy-hitting monsters and bosses, and it is often recommended for players who prefer a more defensive playstyle. In order to activate Guard Up, players need to have the necessary armor and equipment with the skill, and they must also have a sufficiently high level of skill in order to use it effectively.
