Blighted Marsh

For someone who has enjoyed completing Returnal thoroughly and have over 1000 hrs of gameplay. I’m now enjoying Saros however I’m struggling with the Blighted Marsh for the past 3 days. Two enemies that really hurt me, one is that mother pig and the second is that jumping Rhaboom that releases red orbs, these both enemies are fucking killing me too often. Reached Legion thrice, lost at the 3rd phase every time. Not being able to make progress for this long is frustrating. I either use the crossbow or the smart rifle. Also at times I complete Shattered Rise and then jump to Blighted Marsh but it’s always the same story.
