I ask to make the second save in advance because you then know that you loose more strength after a minute (and can roleplay poison eating away your muscle strength during your posts). However DC 11 to both nausea and poison is not that high DC to make (difficult if you lack positive fort save progress but still not impossible).<br/><br/>Also you do not need make any climb check to exit the web where spiders are. Think you need crawl out from trampoline made from webbing (trampoline full of angry spiders). So even if you fail both rolls you can exit the web and spiders leave you alone once your out. Only test after you fell was to break free from entangled webbing before spiders swarm on you and start bite and devour you alive. As even nauseated you can make move action and moving 30'ft is still possible (and you need only move 15'ft to get out if you picked central rope, 10'ft of chose left or right rope passage).
