幻惑 is the noun form meaning 'fascination' or 'bewitchment'; 幻惑的 is the adjectival form describing something that has that quality.
Formed from 幻惑 (genwaku, 'fascination, bewitchment') + 的 (-teki, '-like, -ish'). 幻惑 itself is a Sino-Japanese compound of 幻 (gen, 'phantom, illusion') and 惑 (waku, 'to be perplexed, misled').
