Try not to move too much
Most of the time in games, good agility and movement are rewarded. Here, it's a little different. Yes, moving is still good, since you need to dodge attacks. However, while in motion, you won't be able to fire your bow at enemies meaning you need to balance things out.
You don't need to press any buttons to fire a shot as it's done automatically. However, you will need to stop on a dime in order to let him let loose. So essentially, you'll need to do a lot of stopping and going to get through a level.
Don't worry though, it shouldn't take you long. This is a fast-paced game, so as long as you don't die of course, then you'll be blazing through. Just remember to mix up stopping and going. Do this and you'll be in great shape as you traverse the levels.
Choose your skills wisely
You'll notice that basically after every completed level, you'll be able to choose from a few special abilities to use for the next level. You can choose between three random moves to add to your arsenal for a short time. It can be something like poison arrows for example.
You have some others that allow you to replenish your health too, which is always nice. But it just depends on the situation really. Are you in a spot where you need health? If so, then maybe a health-related option is your best bet, if it's available.
Or, if you want to beef up your firepower, then go with an attack ability. These can be a great way to eliminate enemies quickly. From multi-shot attacks to elemental abilities, there are plenty of ways to take down foes and the bosses. Whatever you choose, they're all great. Just pick the one that you feel benefits you the most.
Make sure to fuse items
The more you play Hunter: Master of Arrows, the more loot you will collect. You will earn them by opening chests which will grant you random rewards. After gathering a few new toys, you will have the ability to fuse them together.
What this does is let you take two or three items, bring them together, and create something new. You'll end up getting something that's more powerful which can really come in handy. Fusing is also a great way to eliminate items that you have more than one of them.
By fusing two of the same things, you'll still end up creating something that's stronger. So go ahead and fuse that extra junk that you have. Someone will see these extras as trash, but for you, this is gold. You can fuse at any time after a session.
